Subject: [PATCH] Cherry-pick 264365@main (698c6e293734).

[JSC] RegExpGlobalData::performMatch issue leading to OOB read
https://bugs.webkit.org/show_bug.cgi?id=254930
rdar://107436732
Reviewed by Alexey Shvayka.
Fixed two issues:
1) In YarrInterpreter.cpp::matchAssertionBOL() we were advancing the string position for non-BMP
characters. Since it is an assertion, we shouldn't advance the character position.
Made the same fix to matchAssertionEOL().
2) In StringPrototype.cpp::replaceUsingRegExpSearch(), we need to advance past both elements of
a non-BMP character for the case where the RegExp match is empty.

Subject: [PATCH] Potential use-after-free in WebAnimation::commitStyles
https://bugs.webkit.org/show_bug.cgi?id=254840 rdar://107444873
Reviewed by Dean Jackson and Darin Adler.
Ensure that the animation's effect and target are kept alive for the duration of this method
since it is possible that calling updateStyleIfNeeded() could call into JavaScript and thus
these two pointers could be changed to a null value using the Web Animations API.
