Bug 1885976 [wpt PR 45174] - Enable missed '.ex-generic' orphaned role tests, a=testonly

Automatic update from web-platform-tests
Enable missed '.ex-generic' orphaned role tests (#45174)

This commit adds calls to verifyGenericRolesBySelector in three test
files, where those calls are missing. There are orphaned role tests
sitting in each file that use the 'ex-generic' class, but since we're
not calling verifyGenericRolesBySelector, they aren't running. This
commit fixes that problem.
