SurfaceFlinger: use scheduler::RefreshRateConfigs in setRefreshRateTo
Use cached values for display configs instead of querying HWC for the
available configs every time we want to change config.
setRefreshRateTo average time reduced from 0.108 ms to 0.032 ms
Test: collected systrace for config changes
