Resolve tiles intent before prompting a dialog for profile selection

Symptom:
Once the work profile component of the tile is disabled after Settings
preloaded tiles, Settings will crash when the user clicks the work
option from the profile selection dialog.

Root cause:
Settings just checks the users from the preloaded tiles to prompt
profile selection dialog. It doesn’t check the activity for the work
profile user before launching.

Solution:
Resolve the activity by intent as users before launching if the work
profile is enabled. Directly start activity if only one user is
resolvable, otherwise prompt a dialog for profile selection.
