Optimize initialization of configuration when display ready

By reordering reconfigureDisplayLocked to the end of displayReady,
it can compute from the related fields at once. That reduces
additional global configuration change at booting.

Also reconfigureDisplayLocked -> sendNewConfiguration
-> updateDisplayOverrideConfigurationLocked already has the same
effect as AtmService.updateConfiguration.

Bug: 301558071
Test: Check the amount of log "Config changes=" when booting.
      Also the fields "hdr", "widecg", "finger" of Configuration
      is updated at the first change.
