app-emulation/wine-vanilla: use new ebuild for 7.0-r3

Based on wine-proton's rewritten ebuild with added logic to handle
additional USE that are being forced in wine-proton but should
be optional here.

7.17 to follow in a bump.

Main goal is to make this hopefully easier to maintain and cleanup
ancient constructs that haven't been relevant in 10+ years. Also
fixes a few misc issues.

List likely incomplete as haven't kept track of everything while
writing wine-proton's ebuild, but for some notable differences
compared to older ebuilds:
- use upstream's way to handle multilib (--with-wine64) to ensure
  wow64 combined build is done as it should
  > like before it still allows 4 types, outline for clarity:
    amd64,  abi_x86_32,  abi_x86_64: full wow64, uses --with-wine64
    amd64, -abi_x86_32,  abi_x86_64: wine -> wine64, no --with-wine64
    amd64,  abi_x86_32, -abi_x86_64: default 32bit-only build, on 64bit
      x86,  abi_x86_32, -abi_x86_64: default with nothing special
- some other differences for ABI handling:
  > use /usr/lib/<variant> for both rather than lib64
  > read CROSSCC_x86/CROSSCC_amd64 on top of wine's CROSSCC
  > CROSS flags check is done per-ABI rather than once for both
  > rely on MULTILIB_COMPAT to set REQUIRED_USE
- force ld.bfd wrt bug #867097 and bug #744829, the various linker
  tricks currently make it unrealistic to use anything else and
  workarounds are insufficient for non-broken runtime even if it builds
  (note can still build with clang, it's lld/mold that lead to issues)
- set QA_TEXTREL wrt bug #746338, seems expected given wine does these
  with -fno-PIC -Wl,-z,notext (aka don't treat DT_TEXTREL as errors)
- fix execstack warnings for stub libraries (likely benign, just noisy)
- handle stripping of PE files manually given portage doesn't know the
  right strip executable to use which resulted in warnings, potential
  mangling, and ignoring .exe/.dll files
- use --<exact> for eselect-wine rather than --all to reduce noise
- nonfatal eselect-wine for prerm, this allows removing wine in the
  event it was already deregistered notably if postinst's eselect-wine
  failed (which gives an error but doesn't fail installation)
- do maintainer-oriented sanity check for matching mono on top of
  gecko's, check is always done regardless of USE and is only nonfatal
  for live version
- various deps revisions, hopefully more pedantic, for some notes:
  > split dlopen'ed deps for clarity, these "could" be runtime
    optfeatures but realistically want wine to work as expected (split
    makes it easier to handle app-portage/iwdevtools' qa-vdb reports
    which gives a list of libraries it believes can be removed... and
    it turns out to be the dlopen list)
  > yacc -> bison, this explicitly looks for bison
  > XML-Simple -> XML-LibXML, it's what winemaker actually uses
  > move extras under X?, per configure.ac they are no-op if X is unset
- IUSE newly enabled by default:
  > gstreamer: crippled without this and is only set by gnome profile
  > mingw: wine been focusing on PE conversions and most distros offer
    mingw builds making users hit unexpected issues if disabled (no
    longer need crossdev for this, so default is more reasonable now)
  > sdl: input devices like gamepads not being functional can be
    unexpected and unclear as to why (albeit desktop profile sets this)
  > vkd3d: matches later versions that have it always  enabled as a
    bundled PE build
  > vulkan: grown in importance and matches already-default opengl
- IUSE newly disabled by default:
  > perl: winemaker/dump are very rarely needed and may pull a chain
    of modules for no reason
  > udisks: unimportant for common usage and handled by desktop profile
- IUSE added (disabled by default):
  > debug: to skip stripping of PE files, like other mingw packages
  > llvm-libunwind: use over libunwind
- IUSE removed:
  > mp3: was a no-op forgotten IUSE
  > oss: this is ossv4 support which needs unpackaged media-sound/oss
    and a patched kernel, makes little sense to expose as USE that
    sometime confuse users (use EXTRA_ECONF=--with-oss instead)
  > realtime: wrt bug #753698, drop dependency on rtkit
  > run-exes: leave .desktop's MimeType alone (force current default),
    not convinced a USE to sed MimeType out makes sense and untrusted
    potentially harmful files are not limited to .exe, could be
    doing this for every .desktop (...don't open untrusted files, or
    use a user patch if really must)
  > threads: leave it up to defaults, no need to touch this
  (dos/samba optfeature'ish USE could make sense to remove but left
   alone for now)
- no warnings if disable mono/gecko defaults, does not feel necessary
- skip some unnecessary cruft, like
  > PATCHES_BIN code, unsure when this was last used
  > QA_DESKTOP_FILE, these are installed by wine-desktop-common
  > PLOCALES, wine been generating po/LINGUAS itself since wine-1.9.5
  > xdg.eclass, updates are done by eselect-wine after putting files
    in a path xdg tools will recognize (meaningless in ebuild)
  > --enable-hal, like tons of --enable-* switches, it wasn't needed
    and only an issue because ebuild used to pass a hard --disable-hal
  > opencl 32bit check, virtual/opencl is different nowadays using a
    glvnd-like loader and it doesn't prevent building support even if
    there's ultimately no backend to load (not our job to check that),
    furthermore the test used eselect-opencl that is gone from the tree
  > env_vcs_vars: the eclass already inform of variables to use even
    in a multi-repo context (and -vanilla is not even multi)
- not skipping l18n man pages + README based on LINGUAS (normally not
  used for this and is small files, use INSTALL_MASK if unwanted)
- no multislot-apploader.patch, haven't found a way in which this
  matters with current layout and scripts seem to use the right slot
- no multilib-portage.patch, need to support multilib-portage was
  already non-existent and got further dropped by a council vote
- no winegcc.patch, unsure if was still relevant with current ebuilds
  but there is no known winegcc build issues with the new one
- always run make_requests to handle patches rather than check md5sum,
  make_vulkan could make sense too but that requires adding python
  logic to the ebuild for something that's normally unneeded
  (make_requests is only optional for vanilla without user patches)
- not using gentoo-wine-patches tarball, debatable but feel there's too
  few patches (and small) to be worth sharing across variants anymore
  (which may need rebasing anyway), and this skips the need to have
  per-developer URI logic/updates to maintain the tarball
  > also drop the hires icon it contained, questionable whether Gentoo
    should even handle this rather than use upstream's
   (ideally ping upstream's issue for attention instead, but could
    consider reinstating if it's really wanted)
- use Wine's new gitlab, has more capabilities (e.g. shallow clones)
- LICENSE update to include bundled libraries, e.g. libpng (not
  unbundled given PE files can't use system's ELF libraries)
- copyright header reset to 2022-only, not based on old ebuilds

Attempted to support tests (which previous ebuilds restricted), but
concluded that skipping enough for a working subset would be too
difficult to maintain, not to mention sandbox violations to fix and
how easily it can hang.
