Message:

Script Loader: Increase styles_inline_size_limit from 20K to 50K.

Benchmarking of initial page loads versus repeat page loads shows there is a greater performance improvement to increase inlining versus the benefits of relying on browser cache.

This new limit is expected to be further refined during beta based on additional testing.

Props westonruter, sabernhardt, poena, aristath, spacedmonkey, adamsilverstein, jonoaldersonwp, peterwilsoncc.
See #63007.
Fixes #63018.
