Part of #8093. Adds support on x64 with AVX2 for:
v128.load8x8_sv128.load8x8_uv128.load16x4_sv128.load16x4_uv128.load32x2_sv128.load32x2_uv128.load8_splatv128.load16_splatv128.load32_splatv128.load64_splatI've changed
wasm_loadon the macroassemblers to take aLoadKindinstead ofOption<ExtendKind>to model the additional vector operations (vector extends and splats), but I'm open to changing that to a different abstraction.
