Switch from allowed display configs to refresh rate range

This completes the recent work to switch from a list of allowed display
configs to a default config + min/max frame rate.

Bug: 142507213

Test: Ran on a device with refresh rate switching, confirmed expected
      60/90 switching behavior when touching the screen.
Test: Launched Google Maps on a device with 60/90 switching, confirmed
      the device stays at 60fps.
Test: Checked dumpsys output, confirmed new display config specs
      formatting looks good.
Test: Ran on a device with refresh rate switching disallowed via the
      ro.surface_flinger.refresh_rate_switching sysprop, and confirmed
      we don't do refresh rate switching.
Test: Ran on a device that doesn't support refresh rate switching, and
      confirmed normal behavior.
Test: Tested surface flinger's display config back door, confirmed it
      still works.
Test: Inspected log output, made sure there's nothing weird.
Test: Ran unit tests for DisplayModeDirector, LocalDisplayAdapter, and
      RefreshRateConfigs.
