[JSC] Enable AVX JIT code generation
https://bugs.webkit.org/show_bug.cgi?id=249322
rdar://problem/103361339
Reviewed by Justin Michaud.
This patch flips a flag so that x86_64 JIT will use AVX if AVX is supported.
This is a part of bringup work of Wasm SIMD on x86_64 where we support SIMD
operation with AVX.
A/B test says neutral on iMac20,1 and MacBookAir8,2 for JetStream2 and
Speedometer2.
