Add default frame rate setting
Add a new priority PRIORITY_DEVICE_PEAK_REFRESH_RATE, and a new config
setting config_defaultRefreshRate which maps to that priority. This
allows an OEM to easily specify a default frame rate different from the
peak frame rate.
Bug: 148978450
Bug: 154648391
Test: - Added new unit tests to verify DisplayModeDirector handles min,
peak, and default refresh rate settings correctly.
- Modified a Pixel 4 to set config_defaultRefreshRate to 60Hz, confirmed
we default to 60, but that an app calling setFrameRate(90) switches us
to 90.
- Confirmed that the "smooth display" and "force 90Hz" options on Pixel
4 work correctly.
- Confirmed Redfin works as it did before - still constrained to 60Hz.
