[ui] Extend trusted origin to support *.proxy.googlers.com hostnames

[bhamiltoncx]

This builds on f2511be to extend support for trusted origins to *.proxy.googlers.com hostnames, which are used in addition to *.c.googlers.com hostnames.

I extended the unit tests to cover this and confirmed the tests pass with ./ui/run-unittests.

@primiano can you please take a call on this? Should we be doing this at all?

For more context, currently we can't test any Google code which opens a tab to ui.perfetto.dev and posts the Perfetto protobuf over to the other tab. The origin has changed to *.proxy.googlers.com, so it doesn't pass this check.

Without this, ui.perfetto.dev loads but it ignores the message from the other tab.

I'm not 100% sure what the trusted origin logic was originally about, but it's been around for a long time.

I know but it was a convenience hack which we probably shouldn't have done in the first place honestly.

Makes sense. Hopefully there's an alternative for testing code which opens a Perfetto tab. If not, a lot of code will go untested.
