Add a chromium_builder_perf target.

Add a chromium_builder_perf target.

Create a chromium_builder_perf target for all platforms
which refers to projects the Chromium Perf bots use to
test Chromium's performance.  This is a reduced target
to allow the perf bots to cycle faster (builder builds
fewer targets and bots download smaller archives).

Add crash_service to test_support_ui and remove
it from projects that depend on test_support_ui.
This allows projects that just build page_cycler_tests,
startup_tests, etc on Windows to get crash_service.

BUG=70580
TEST=all continues to work, chromium_builder_perf works,
builds crash_service on windows
