misc: chore: annoyed I missed this, it's very obvious

Instead of one big 2048MB JIT Cache that'd crash the emulator when maxed
out, we now have it where we add 256MB JIT Cache regions when needed,
helping reduce allocated memory where games don't use the JIT cache for
it, and helping bigger games that DO need JIT cache bigger than 2048MB!

(SSBU goes past the 2048MB JIT Cache limit that would normally crash
Ryujinx ^)

Also I added a BSD socket that Baba is You's networking for downloading
custom levels uses.
