[externals] FFmpeg -> v8.0-be99d2c0b2, OpenSSL -> v3.6.0-e3608d80df, SDL2 -> 2.32.10-38e0094637 (#3003)

FFmpeg:
- builds for FreeBSD, OpenBSD, Solaris
- minsizerel
- Proper system lib linking on MinGW
- removed shared stuff entirely outside of android because their build system SUCKS

OpenSSL:
- macOS universal
- Proper system lib linking on MinGW

SDL2:
- macOS universal

Both are now based on branches/commits rather than tags (since their respective release branches have a ton of new stuff lol)
