app-emulation/wine-staging: support building with mingw64-toolchain

This allows USE=mingw to be usable without manually using crossdev
first to ease usage for users and automated testing.

Old behavior using crossdev still available with USE=crossdev-mingw,
albeit new one should offer better stability given mingw64-toolchain
is intended/tested especially to build wine+dxvk+vkd3d-proton.

Given wine is pushing PE conversions and some things work better with
PE files (e.g. Blizzard games, Proton also uses --with-mingw), it may
be useful for the prospect of making this a default at some point.

Note that mingw64-toolchain's ${MULTILIB_USEDEP} does belong in BDEPEND
(unless <EAPI-7), as it'll use cross libraries located in BROOT.
