Add GC APIs

[phated]

Binaryen 111 added C APIs for most GC-related functions, such as:
WebAssembly/binaryen@version_110...version_111#diff-5d2db7a99567fbac5e617fd39709fbdca0a2d22b92a97d5c3515caf7dba9f78bR1035-R1154 and WebAssembly/binaryen@version_110...version_111#diff-5d2db7a99567fbac5e617fd39709fbdca0a2d22b92a97d5c3515caf7dba9f78bR2335-R2706

However, they left them all as TODO in the JS code (see WebAssembly/binaryen@version_110...version_111#diff-9f4ceff4b9bcc272e133f83651e487c15f772e6115c88023c2435cc5226d8b68R2438-R2448)

We generally don't want to bind to things that can't be bound in JS, so we should check to see if these APIs were added in v112 and implement them when available.

It also seems like we need to implement an API for the "type builder" API in binaryen.

The gc-related instructions are still marked as todo in version_112 from what I can tell https://github.com/WebAssembly/binaryen/blob/728b37cbe95ca8ea8cfba9ebc70e3fcb14db273a/src/js/binaryen.js-post.js#L2430-L2440
