WebIDL codegen: Replace cmake with a single Python script
When [playing around with Cargo’s new timing visualization](https://internals.rust-lang.org/t/exploring-crate-graph-build-times-with-cargo-build-ztimings/10975/21), I was surprised to see the `script` crate’s build script take 76 seconds. I did not expect WebIDL bindings generation to be *that* computationally intensive.
It turns out almost all of this time is overhead. The build script uses CMake to generate bindings for each WebIDL file in parallel, but that causes a lot of work to be repeated 366 times:
* Starting up a Python VM
* Importing (parts of) the Python standard library
* Importing ~16k lines of our Python code
* Recompiling the latter to bytecode, since we used `python -B` to disable writing `.pyc` files
* Deserializing with `cPickle` and recreating in memory the results of parsing all WebIDL files
----
This commit remove the use of CMake and cPickle for the `script` crate. Instead, all WebIDL bindings generation is done sequentially in a single Python process. This takes 2 to 3 seconds.

Remove outdated test result files automatically
This builds off the of suggestion from #24292 to add a script that is run every WPT sync to remove any useless WPT test result files. It does not subsume that PR because that one includes some manual removals of subtest results inside ini files that are still meaningful.

Update a bunch of stuff to syn 1
This updates a lot of our crates to syn 1. Not all of them, but syn 1 was already in tree so it doesn't matter much either way.

Remove use of packed_simd
This crate takes about 40 seconds to build of a fast desktop, and was used in exactly one place. Additionally, that use was previously accidentally disabled (a553964123) and we only noticed more than a year later when the build broke (d1efad6763).
