Topic: wasmtime / PR #6629 x64: Fix ISA requirement for `pmaddubsw`

alexcrichton opened PR #6629 from alexcrichton:x64-sse2-pmaddubsw to bytecodealliance:main:

This was erroneously listed as SSE2 but this is actually an SSSE3 instruction. This commit updates the ISA requirement as well as related lowerings to have everything work with an SSE2 baseline as well which is mostly plumbing to make sure the relaxed-simd dot product instructions use it when it's available but otherwise fall-back to the deterministic lowering.
