Bug 1799179 - Add multi-suite test categories to perf selector. r=per…

…ftest-reviewers,kshampur

This patch adds 4 new categories of tests to the perf selector: DAMP tests, Talos tests, Graphics, & Media Playback, and Resource Usage tests. Each of these use a different suite (talos), and one of them also makes use of AWSY. Some extra code needed to be added, and the existing setup that we use for categories had to change to handle the case of a category using multiple suites.

The Resource Usage category has the most going on in it. A few new fields are added to allow categories to specify/restrict where they can run (platform, variants, and app).
