commit c9cee7e5db8b778279bf39c3a249ab1140616b83

Get performance_browser_tests working again.

Fixes:

1. The timestamp field in the event traces has been made consistent
(between the Capture and OnBufferReceived trace events). This allows
pipeline tracking of individual frames (and fixes the 97-100% drop rate
bug).

2. Add BUILD.gn target dependencies to build browser PAK/resources that
are required in order to run the binary.

3. Allow thread-blocking in media::cast::test::UDPProxyImpl.
