Re-enable MediaEngagementAutoplayBrowserTest.UsePreloadedData_Allowed

It was disabled on all Linux platforms due to failures on Chrome OS
in SingleProcessMash browser_tests.

Instead, disable all MediaEngagement browser_tests via filter file
for SingleProcessMash. There's a fix in-flight for renderer
embedding in this mode, so I expect to re-enable them shortly.
