Skip invoking bindgen if no header changes
This can avoid doing bindgen when build script is called for updating other files, e.g. properties.
This uses a global modified time, so there is a chance that some of the files which can be skipped but not skipped. But given that we do all three files in parallel, that would unlikely affect the actual runtime.
Using lots of `Mutex` could be an issue, but it doesn't seem to be in practice. Since only one thread would hold the lock of `ADDED_PATHS`, there is never a competitor for the lock of `LAST_MODIFIED`.

Interpolate colors with premultiplied alpha.
We need to clamp each interpolated values because some cubic-bezier functions
produce values that are out of range [0, 1].

Flexbox trace
<!-- Please describe your changes on the following line: -->
This is a follow up for #13740, so r? @jdm
The first patch enables JSON serialization for flexbox flows, the second one fixed format incompatibilities for the layout viewer.
The 3rd and 4th patches are just layout viewer UI enhancements, we could split that to a spearate PR if you prefer.

Fix inline layout of table cells impacted by rowspan
This is part of the fix for #11297. This PR fixes the inline layout of table cells impacted by row-spanning cells from previous rows. A separate PR to follow will fix the table block size calculations to account for rowspan.
This PR doesn't yet include any test changes. If it doesn't cause any existing tests to pass, I will add a new test to it.

It turns out that it's problematic to embed ThreadLocalStyleContext within
LayoutContext, because parameterizing the former on TElement (which we do
in the next patch) infects all the traversal stuff with the trait parameters,
which we don't really want.
In general, it probably makes sense to use separate scoped TLS types for
the separate DOM and Flow tree passes, so we can add a different ScopedTLS
type for the Flow pass if we ever need it.
We also reorder the |scope| and |shared| parameters in parallel.rs, because
it aligns more with the order in style/parallel.rs. I did this when I was
adding a TLS parameter to all these functions, which I realized we don't need
for now.
