Parameterize accessibility "dump" tests

The accessibility dump tests (both tree-dump and event-dump) execute
multiple passes for each test.  Most OSes run two passes (Blink +
Native), but on Windows we recently introduced a third pass for UIA.

The addition of the UIA pass required that we toggle an experimental
command-line flag to ensure that UIA is properly enabled/disabled.

Unfortunately, modifying the command-line multiple times during the
test ran afoul of the ThreadSanitizer, which reported a data-race
condition.  This required that the dump tests be parameterized, so that
each "pass" now runs independently, and can update their command line
only once.

Note: "gtest_filter" now requires a "/xxx" suffix, e.g.:
   --gtest_filter=DumpAccessibilityEventsTest.ValueValueChanged/*
