Update geckolib build-time bindgen build script for recent regex changes.
`./mach build-geckolib --with-gecko ...` is broken due to regex's API changing a bit.

Only create scrolling overflow regions when necessary
Only create scroll roots for overflow regions when the overflow region
is actually larger than the container size. This prevents creating
scrolling roots for elements that do not have overflow scroll as a
side-effect of the way their height and width is defined. For example,
tables should never respect overflow:scroll since their height and
width should always be large enough to prevent overflow. This also
decreases the size and complexity of the display list in many other
circumstances.
As part of this change, transformed overflow calculation is moved from
display list construction to layout. This should mean that overflow is
handled more accurately earlier.
Fixes#14574.

Cleaning up CalcLengthOrPercentage
<!-- Please describe your changes on the following line: -->
We don't really need enum variants in `CalcLengthOrPercentage`. Given that we already have the information (whether it's `vw`, `ch`, etc.) in the struct fields, we could just store `Option<CSSFloat>` there, and modify our `ToCss` implementation a bit.

Bug 1331272: style: Unify restyle-damage display: none checks.
They were formerly different because we used the element check to cull the
traversal.
Now this is no longer true, so we can just unify them.
Also, update a no-longer up-to-date comment on that.

Enable codegen-units=4 in debug mode
We previously had this and removed it because it caused runtime slowdowns
(discussion in #11102), but that was in release mode.
Debug mode is already very slow at runtime.
In my opinion, debug mode is mostly for the edit-compile-test cycle
which is currently dominated by compile times, so sacrificing runtime for compile time makes sense.
I’ve observed a ~30% improvement of compile times with this. This figure is consistent between a very fast desktop with 4 cores / 8 threads and a not-as-fast laptop with 2 cores / 4 threads.
