Issue #2053 - Part 3: Update PerformanceMark to User Timing L3

There are a few minor differences between this and Mozilla's implementation:
(a) The type error messages were not hardcoded to the Performance class and were moved to Errors.msg or domerr.msg instead.
(b) Resist fingerprinting-pref changes were skipped.

Partially based on https://bugzilla.mozilla.org/show_bug.cgi?id=1724645
