This commit updates the `wasi-sdk` download used by the `wasm32-wasi*`
targets. The motivation for this commit is generally just "keep things
up to date" and is not intended to cause any issues or differences from
before, just a routine update.

The updated wasi-sdk has debuginfo by default so be sure to strip the
debuginfo by default when testing the size of new executables.

The existing implementation uses Python to launch a set of Rust-written
binaries. Unfortunately, this is currently broken; it seems that some
updates meant it no longer compiles.

There is also a problem that support for more float types (`f16`,
`f128`) would be difficult to add since this is very specialized to
`f32` and `f64`.

Because of these sortcomings, migrate to a version written in Rust. This
version should be significantly faster; test generators can execute in
parallel, and test cases are chunked and parallelized. This should also
resolve the preexisting "... the worker processes are leaked and stick
around forever" comment.

This change also introduces genericism over float types and properties,
meaning it will be much easier to extend support to newly added types.

`num::BigRational` is used in place of Python's fractions for
infinite-precision calculations.

Since `test-float-parse` is now implemented in Rust, we can move it into
the global workspace and check dependency licenses.

With updates to `test-float-parse`, it is now possible to run as another
Rust tool. Enable check, clippy, and test.

Test runs the unit tests, as well as shorter parsing tests (takes
approximately 1 minute).

With the previous improvements, it is now possible to run float parsing
tests as part of CI. Enable it here.

This only runs a subset of tests, which takes about one minute.

Promote Mac Catalyst targets to Tier 2, and ship with rustup

Promote the Mac Catalyst targets `x86_64-apple-ios-macabi` and `aarch64-apple-ios-macabi` to Tier 2.

Draft until [the MCP](rust-lang/compiler-team#761) finishes (see that for motivation).

Rewrite `test-float-parse` in Rust

Migrate from the currently broken Rust + Python `test-float-parse` to a Rust implementation. This newer version should be significantly faster (tests execute in parallel with threads, rather than series across multiple processes, which also eliminates the "...the worker processes are leaked and stick around forever" message), and should be significantly easier to extend to the new float types.

Since this is faster and hopefully more stable, we should be able to launch it with `x` and run the faster tests in CI.
