Do not abort launch logger by invisible drawn activity

For a special complex case: A no-display trampoline activity
launches main activity in the same task (no starting window),
and then the main activity launches trampoline and main again
consecutively. If the drawn event of main is reported before
the 2nd launch of main, the launch event log will be canceled
by seeing the drawn state before transition.

Because there will be a transition to commit window visibility,
the case can be addressed by allowing invisible drawn activity
as a valid launch event. Then the launch time can be reported
when notifying transition starting.
