[Selection] Avoid to inline SmartSelectionMetricsLogger on below P

No logic change, add @VerifiesOnP and make the version check at call site
of SmartSelectionMetricsLogger.create(), hopefully it will not try to
load SmartSelectionMetricsLogger class on below P, so it will avoid
class verification failure on below P.

Bug: 1021642
Test: Current tests should pass.
