  [JSC] Remove Wasm BBQ Air code generator
https://bugs.webkit.org/show_bug.cgi?id=261042
rdar://114832639

Reviewed by Keith Miller.

This patch removes Wasm BBQ Air code generator. We landed new single pass WasmBBQJIT 6 months ago,
and it already gets stabilized. Many code already started assuming this new WasmBBQJIT, and new
features (like, WasmGC etc.) are only implemented / tested on new WasmBBQJIT now.
Also, this significantly reduces JSTests variations since it has many conditions running tests with
Wasm Air flag, which mode is not used in ARM64 / x64 anymore.

We also remove many Wasm BBQ Air code generator related flags, and rename useSinglePassBBQJIT to useBBQJIT
since now this new WasmBBQJIT is the only canonical BBQJIT.
