Fix DisplayWindowSettingsTest to restore overscan settings

Browse Source 
This CL restores overscan settings to default values after finishing tests
that modify overscan settings of primary display. This CL also fixes
DisplayWindowSettings#applySettingsToDisplayLocked(DisplayContent) to be
able to apply default settings value.

With this CL, we can reuse WindowManagerService instance among all
WindowTestsBase tests.

Fixes: 121296525
Test: Pass all presubmit tests in WmTests.
