Add since_visible_millis to Settings action logs.

This change adds a new action logging method on MetricsFeatureProvider
within Settings.

Uses the VisibilityLoggerMixin to calculate the elapsed time since
the fragment has been visible. Adds tagged data in
MetricsFeatureProvider#action() to store this elapsed time in
NOTIFICATION_SINCE_VISIBLE_MILLIS in MetricsEvents. Modifies the
LogWriter interface to accept variadic taggedData args in its action()
methods. Annotates the old subtype #action() methods as deprecated.

EventLogWriter also no longer casts the subtype values to strings before
sending them to MetricsLogger, so they are correctly stored as subtype
instead of package.
