script: Ensure notify_invalidations() is always called when modifying stylesheets (#38530)

Browse source 
This change supplements the missing stylesheet invalidation
notifications to fix some bugs that the modification of stylesheet does
not take effect. Additionally, this PR add a RAII thing to mark the
modification scope of stylesheet rules, which will facilitate to add
extra logic before the modification happens.

Fixes: there is relevant issue #38211 , but it can't be fixed by this
PR.
Testing: This fixes some subtests in
`/css/cssom/CSSStyleSheet-constructable.html`.
