Introduce type checking with Pyrefly in `components/script_bindings`
This commit adds Pyrefly-based type checking to the
`components/script_bindings` directory. The primary goal is to catch
type inconsistencies early and reduce the likelihood of unexpected
runtime errors.
This change affects the `webidl` component, as these script bindings are
responsible for connecting WebIDL specifications to the Rust codebase.
Testing: `./mach test-wpt webidl`

to use the [SpiderMonkey Debugger
API](https://firefox-source-docs.mozilla.org/js/Debugger/), we need to
call it from an internal debugger script that we will supply. this
script must run in the same runtime as the debuggee(s), but in a
separate
[compartment](https://udn.realityripple.com/docs/Mozilla/Projects/SpiderMonkey/Compartments)
([more
details](https://hacks.mozilla.org/2020/03/future-proofing-firefoxs-javascript-debugger-implementation/)).
when creating two globals in the same runtime, Servo will generally try
to reuse an existing compartment for the second global, and there are
other places in script where we rely on this reuse. but for the debugger
script, we can’t do this.
this patch adds a `use_system_compartment` flag to global object
descriptors, which isolates the global in its own compartment in both
possible directions:
- it forces the global to create a new compartment, preventing the reuse
of any debuggee’s compartment
- it fails the check in select_compartment(), preventing future
debuggees from reusing the global’s compartment
Testing: manually tested working in devtools debugger patch (#37667),
where it will undergo automated tests

Renames the files to pythonic file names. Also replaces the bespoke
caching function with the functools caching function which is
functionally equivalent.
