stylo_test's build script is split between Python and Rust. style's
build script already has to perform complicated dances to determine an
appropriate binary to execute, depending on the platform. To avoid
copying and pasting that code, it seems reasonable to simply port the
Python code into Rust, thus making the relationship between generated
files and the cargo dependency output clearer. The new Rust is somewhat
more verbose, but not terribly so.

Script paint worklets speculative evaluation
<!-- Please describe your changes on the following line: -->
This PR speculatively calls paint worklets during style, which increases the concurrency, since it increases the chance that the cache will have the right result in it when it comes to layout. The speculation is wasted effort if the size of the element has changed, but this is often not the case.

style: Don't remain in an invalid state when encountering an at-rule in the wrong place.
Currently, attempting to parse an at-rule that is out of place, such as
an @import rule after a regular style rule, will cause the parser state
to be set to Invalid. This will cause any following at-rule to be
rejected until we encounter a regular style rule, at which point we'll
go back to the Body state. There's nothing in the CSS specs about
needing to reject all following at-rules (or, as the comment above
Invalid says, ignoring the entire rest of the style sheet).
