Intermittent leaks with js_arena_realloc and CompileUtf8 have started
showing up to leaks involving a bunch of JS stuff, so add them to the
top-level LSan WPT white list.

The only visible change from this change is that telemetry will be
discontinuous. The owners for the relevant telemetry probes have
reviewed this and indicated that this discontinuity is OK.
This adds two new properties to wpt metadata files:
mozleak-allowed - This is a list of the form [process-name:object
name], which indicates objects that may be leaked in that specific
process. Automatic updates that find a leak may add that object to
this list.
mozleak-threshold - This is a list (but conceptually a map) of
[process-name: threshold bytes], indicating a threshold below which
leaks will not cause a test failure. This number is updated by setting
it to the observed value for a process.
