[JSC] Further optimize wasm init time
https://bugs.webkit.org/show_bug.cgi?id=287076
rdar://144217504
Reviewed by Keith Miller.
This patch further optimizes wasm init time.
1. addCall's signature is already expanded, so we do not need to do it
again.
2. CallInformation should hold numberOfStackValues for wasm.
3. IPIntGenerator MetadataBuffer increase policy should be 2x.
4. We introduce CallCommonData bytecode cache.
5. Use shrink(0) instead of clear() for control flow stack in IPIntGenerator.
6. Do style fix.
