[WebAssembly][NFC] Reorder SIMD sections

[tlively]

Summary

Reorders the sections in the SIMD tablegen file to roughly match the
new opcode ordering. Depends on D54126.

[aheejin]

LGTM. Maybe you need to rebase it on top of D54126 if you end up changing something there.

• Rebase for new numbering
