Add chrome perf tests to GN build, fix harfbuzz

This also hooks up the chrome test support target which was previously not compiled (the file wasn't referenced).

This duplicates the harfbuzz logic from the GYP build where the system one is conditionally used if the pangoft2 version is sufficiently large. There are some additions to the pkg-config wrapper script to check versions.

Write a service_discovery_sniffer target but don't hook it up. Currently this gives linker errors.

Fix grit warnings for the remoting resources.
