Bug 1507660 [wpt PR 14084] - [UserTimingL3] Fix meature, mark API feature detection, a=testonly 

Automatic update from web-platform-tests[UserTimingL3] Fix meature, mark API feature detection

UserTimingL3 uses returned value for feature detection. If measure and mark
API returns null, the APIs are L2 API; If the APIs return an entry, the APIs are
L3 API. However, in the current implementation, when L3 API is enabled, the
APIs do not always return the created entry.

This CL is to fix this bug, and add layout tests to verify it.
