Use chromium_linux_and_gl_gtests on fewer bots.

"Out of Process Profiling Linux" used chromium_linux_and_gl_gtests and then
removed of the suites added by _and_gl via test_suite_exceptions again.
Instead, just use regular chromium_linux_gtests for it. No behavior change.

"ToTLinuxThinLTO" used the _and_gl version and removed gl_tests again.
It didn't remove gl_unittests, but that one was failing on it. So just
use chromium_linux_gtests here too.

"ToTLinuxUBSanVptr" and "UBSanVptr Linux" were removing gl_tests (but not
gl_unittests) via the exceptions file despite not (yet?) using the _and_gl
test list, so remove these unused exceptions.

Add a comment explaining why interactive_ui_tests doesn't run on the ubsan
bots (probably it should run there, with just the few failing tests disabled).
