feat!: upgrade wasmparser & wasm-encoder to v0.212.0

[lwshang]

Description

It is inevitable to introduce breaking changes so that we can make this project catch up with recent Wasm standard (and proposals).

New types

• RefType is now a separate type which covers Funcref and Externref used to be in ValType
• ElementItems which covers both Functions and Expressions

Types that have significant change

• InitExpr => ConstExpr
• Element: add item: ElementItems
• Global: add shared: bool
• Memory:
  • add memory64: bool
  • u64 for initial and maximum
  • add page_size_log2: Option<u32>
• Table:
  • add table64: bool
  • u64 for initial and maximum

Wasm Feature

In module/mod.rs:

Fix wasm_features from wasmparser::WasmFeatures::default() regardless of config.only_stable_features.

Spec tests

• Update the spec-tests (WebAssembly/testsuite) submodule
• Reflect the latest set of Wasm proposals
• Now run all core tests and the multi-memory proposal tests
• Remove outdated special cases
• Collect and show all failed test cases instead of only the first one

CI

Use the latest pre-compiled wabt and binaryen.

Thanks for the PR! I'll gladly do a review and merge here further.

Are you able to get the remaining tests passing for this?

@guybedford

All CI checks have passed! Could you please review and merge my PR when you get a chance?

Next up, I'll be working on the "memory64" feature in a new PR soon.

This is great work, thank you for getting this one over the line. Just a couple of comments on the TODOs then it would be great to land and release this.
