Remove http/tests/w3c

This CL moves the final user-timing tests to external/wpt and removes
the folder. The performance_entrylist_checker is changed as in the http
counterpart to allow de-duplicating test messages.

There are some tests that are related to the wpt counterparts, but not
equivalent and in a different format, so unifying some of these tests
can be done in the future.

-Tests are now imported into LayoutTests/imported (see README there).

-The tests in LayoutTests/http/tests/w3c/webperf were imported from

-* resource-timing -> resource-timing/
-* UserTiming -> user-timing/
-
-This directory now contains:
-
-* Submissions that were not "approved" - these should be reviewed
-  for redundancy with approved tests in web-platform-tests
-
-* Tests that require a http/s server. Tracked as:

-With only one exception (below), these files should not be modified directly. Instead, please
