profiles: consolidate arch/riscv files

Now this is the big and ugly one. Since the 17.0 profiles are gone now, we can
simplify...

* All information from riscv/rv32imac and riscv/rv64gc is moved into their
  subdirs; these two are not valid profile dirs anymore.
* A new subdir riscv/rv64gc/lp64d-multilib is created as replacement.
* We do not by default pull in multilib and disable it then everywhere anymore.
  Instead we only pull in multilib in the riscv/rv64gc/lp64d-multilib dir.

* The make.defaults in riscv specifies the two-level libdirs used ONLY
  for multilib secondary ABI (i.e. in practice never except when experimenting).
  The libdir for the primary, default ABI MUST be overridden in the specific
  profile to a single-level path.
* This makes the need for the 1level directory go away.

* We use for the default ABI "lib64" (64bit) or "lib" (32bit) to keep the
  structure of other arches, as also stated in the specs as fallback.
  Note that the 2-level libdirs for 32bit remain lib32/*; using lib/* here
  does not work.

* default/linux/riscv now pulls in arch/riscv,
  default/linux/riscv/20.0/rv64gc and default/linux/riscv/20.0/rv32imac
  build on that but add no further arch dir.
