database/sql: scan into *time.Time without reflection

Previously scanning time.Time into a *time.Time required reflection.
Now it does not. Scanning already checked if the source value was of
type time.Time. The only addition was checking the destination was
of type *time.Time.

Existing tests already scan time.Time into *time.Time, so no new
tests were added. Linked issue has performance justification.

Fixes #22300
