Bump wasm-tools crates (#7094 )

* Bump wasm-tools crates

Two major changes/reasons for this update:

* Primarily pulling in support for semicolons-in-WIT files. Semicolons are
  not currently required, though, so I'll follow-up later with actual
  semicolons.

* The syntax for parsing `(if ...)` was fixed in `wast`. Previously it
  did not require `(then ...)` but this is required by the spec. New
  spec tests require this as well. This breaks existing text format
  tests which don't use `(then ...)` inside of an `(if ...)`. Most tests
  were updated by hand but `embenchen_*` tests were updated by running
  through the old parser to produce non-s-expression using code.

* Fix an example `*.wat`

Update the spec reference testsuite submodule (#3450 )

* Update the spec reference testsuite submodule

This commit brings in recent updates to the spec test suite. Most of the
changes here were already fixed in `wasmparser` with some tweaks to
esoteric modules, but Wasmtime also gets a bug fix where where import
matching for the size of tables/memories is based on the current runtime
size of the table/memory rather than the original type of the
table/memory. This means that during type matching the actual value is
consulted for its size rather than using the minimum size listed in its
type.

wasmtime: Implement `table.get` and `table.set`

These instructions have fast, inline JIT paths for the common cases, and only
call out to host VM functions for the slow paths. This required some changes to
`cranelift-wasm`'s `FuncEnvironment`: instead of taking a `FuncCursor` to insert
an instruction sequence within the current basic block,
`FuncEnvironment::translate_table_{get,set}` now take a `&mut FunctionBuilder`
so that they can create whole new basic blocks. This is necessary for
implementing GC read/write barriers that involve branching (e.g. checking for
null, or whether a store buffer is at capacity).

Furthermore, it required that the `load`, `load_complex`, and `store`
instructions handle loading and storing through an `r{32,64}` rather than just
`i{32,64}` addresses. This involved making `r{32,64}` types acceptable
instantiations of the `iAddr` type variable, plus a few new instruction
encodings.
