games/retroarch: update to 1.8.5 (and add WAYLAND option, fix powerpc64, etc.)

This is mostly Greg's patch,
I have added the new ports to games/Makefile (missing from PR, SUBDIR+=),
and fixed a few spaces-vs-TAB glitches in the makefile,
and reformatted the pkg-descr, and changed libretro-shaders-slang/pkg-descr to:

| Vulkan GLSL RetroArch shader system
|
| WWW: https://github.com/libretro/slang-shaders

v1:

Here's 1.8.5.

v2 of 1.8.5 update:

- Fixed stage-qa (python/shebangfix)
- Moved fPIC from port variable to PR/patch:
  https://github.com/libretro/RetroArch/pull/10384
- Fixed build with security/rhash installed:
  https://github.com/libretro/RetroArch/pull/10382
- Fixed ifdefs to solve powerpc64 issue:
  https://github.com/libretro/RetroArch/pull/10383
- Made X11 an option
- Added libcaca option (the build system was auto finding this for me)

v3:

One little revision, fixing the dependency on libwayland-egl,
which has been living in wayland instead of mesa for a long time.

v4:

Rebased after the webcamd/v4l related update

Test built in poudriere 11.3 i386 and 12.1 amd64.
