[Extensions] Use compiled feature files

extensions/test/BUILD.gn

I wonder if it make sense to just move these targets into //extensions/BUILD.gn
.

The advantages would be that you wouldn't need "../" in the sources (which is an
uncommon thing in GN, though allowed), and you wouldn't have the stuttering in
the GN labels, e.g.: //extensions:test_api_features vs.
//extensions/test:test_api_features .

Alternatively, you could maybe also rename the targets to just "api_features",
etc.?

I think I'll save this for a followup.  The gn rule currently uses the target
name to create the file, so it'd be a little more than a quick change.  Also,
even if we did it here, we'd still need the ../s in the
chrome/common/extensions/api version.  It could be worth investigating, but I'd
prefer to land this one like this for now.
