Add UKM metrics for UpdateLayers and ProxyCommit
The begin main frame UKM system captures all major tasks in
ProxyMain::BeginMainFrame except for LayerTreeHost::UpdateLayers
and the ProxyMain commit of the layer tree to the impl thread.
This patch adds those missing UKM metrics. The aggregator is
modified to only create UMA counters for some metrics because
UpdateLayers has it's own UMA metrics with additional context that
we can't replicate in a clean way.
