[X86] BuiltinsX86.td - attempt to pack the builtins for each SSE level close together. NFC. (#168844)

Avoid some repeated feature blocks - we should have a single place in
each file that we can find most builtins for a particular ISA level.

Also, avoid some of the 80col wrapping that just makes it harder to find
anything at all.

There's a lot more we can do - but I don't want to completely refactor
this while we still have so much work to do for #30794
