No official Pale-Moon changes picked since my last build.

No official Basilisk changes picked since my last build.

My changes picked since my last build:
- js: HACK to remove call to IsAboutToBeFinalizedDuringSweep(), since gcWeakRefs will be cleared later regardless remaining entries, check here is meaningless (8a2d52ae32)
- js: BIGUGLYHACK not to trigger debugbreak if VirtualProtect fails (926096361d)

Update Notice:
- You may delete file named icudt*.dat and icu63.dll inside program folder when updating from old releases.

* Notice: From now on, UXP rev will point to `custom` branch of my UXP repo instead of MCP UXP repo, while "official UXP changes" shows only `tracking` branch changes.

New build of post-deprecated Serpent/moebius for XP!
