SF: change the render frame rate when a display mode is changing

Set the render frame rate to the physical display refresh rate so
we could schedule the frame that initiates the mode switch quicker.

Test: atest open-fixed-calculator --rebuild-module-info --tf-template metric_post_processor=google/template/postprocessors/metric-file-aggregate.xml --aggregate-metric-filter source_event_delay_millis_com.google.android.calculator-mean
