Add a data URL resource loader performance test
https://bugs.webkit.org/show_bug.cgi?id=235325
Reviewed by Eric Carlson.
This patch is a follow-up of r287899. In local tests, the time taken
by a video element to load a data URL is about 2x of the time to load
the binary form of the media file.
* media/video-src-blob-perf-expected.txt: Added.
* media/video-src-blob-perf.html: Added.
