This is part of #16982.
Right now we have some code that tries to cache stuff in the style data during
layout.
This code is extremely rarely executed, only for `<details>` and `<summary>`.
I think if we really really want to cache these, we should find a place in the
layout data for it.
For now, let's move it away (and all the other layout code) from mutating the
style data from layout.
For now, only impls for types like in style::values::generics can be derived.
This also needed a few ToComputedValueAsSpecified impls that I would like to
replace by some #[to_computed_value(clone)] attribute, but I think it is ok
to keep it like this for now.

style: Move all the style sharing code outside matching.rs
This is just a code health change. I want to move it away to keep matching.rs as
simple as possible.

Now that MinGW and MSYS have been removed from the Windows builders,
bash is not available to run the previous upload_nightlies.sh script.
Convert the script to Python 2 for cross-platform support.
Additionally, switch to the `boto3` library for easy uploading
without needing to install `s3cmd`,
and move the code into mach for easy `boto3` installation
as the new `./mach upload-nightly` command.
Also, hard-code the paths to the packages instead of using
globs to look for them, as the paths are static.
(The paths used to contain timestamps,
but we now insert timestamps when uploading to S3
to improve reproducibility.)
