Add gpu accelerated config changes to SmokeTests.
SmokeTests are the subset of layout tests run on the android bots. This change
adds coverage to several historically problematic config-change scenarios.
These tests use a virtual suite that sets the flag "--use-gpu-in-tests". This
flag overrides the default test behavior of using MesaGL, which is not capable
of creating surfaces to use with gpu accelerated decoding (at least on Android).
This change also fixes some test/expectations rot.
