Update SingleProcessMash browser_tests filter

Pull in entries from the Mash filter file, for tests that are also failing in
Mash.  Also broadens filter coverage for some test classes using wildcards,
to reduce the chance of a failure from a flakiness or new tests being added.

Mash: initialize kTopViewInset on app windows

This is necessary so the initial bounds can be calculated correctly.
The app window requests a size for the content bounds and
ClientSideNonClientFrameView tacks on kTopViewInset.

Notes: Check failed: (*mdp_iter)->task_runner && (*mdp_iter)->task_runner->RunsTasksInCurrentSequence(). MemoryDumpProvider "ContextProviderCommandBuffer" attempted to unregister itself in a racy way.

crrev.com/c/1212093 blacklists all EncryptedMediaTests until the race condition is addressed.

Ryan, are those tests racy in the non-mash browser_tests too?

@sky: these EncyptedMediaTests don't look flaky on the non-mash (regular) browser_tests.  See https://test-results.appspot.com/dashboards/flakiness_dashboard.html#sortColumn=test&sortOrder=forward&builder=chromium.chromiumos%3Alinux-chromeos-rel for a sorted list of tests, and search for "EncyptedMediaTests".

This search actually uncovers a few other types encrypted media tests that need to be blacklisted.  Will send a CL for that shortly.

Also, once the SingleProcessMash browser_tests are added to the main waterfall we'll be able to track the flakiness of individual tests with the flakiness dashboard.

Marking as fixed, now that the tests are running on the main waterfall/CQ.

CrSettingsResetPageTest.All is flaky regardless of mash.
