Non-visible layers are now "inactive"

When setting "explicit_refresh_rate_hints", we saw the perfetto trace is
very noisy in LayerHistory/RefreshRateSelector. This change fixes this
in a few ways:
- Non-visible layers should now be inactive in LayerHistory. This should
  be safe because non-visible layers were treated as NoVote,
  and does not affect the refresh rate chosen.
- LayerInfo for ExplicitCategory now considers NoVote (from non-visible
  layer).
- RefreshRateSelector::calculateLayerScoreLocked does not have any
  interesting trace calls itself, so remove its ATRACE_CALL.
