Show empty state screens in order of priority.

To improve the user experience, this CL changes the order
in which the empty state screens are shown:
1. (highest priority) cross-profile disabled by policy
2. no apps available
3. (least priority) work is off

The intention is to prevent the user from having to turn
the work profile on if there will not be any apps resolved
anyway.

Fixes: 150936283
Test: atest ResolverActivityTest
Test: atest ChooserActivityTest
Test: manually tested each possible combination of edge cases
(work profile off, no apps found, cross-profile intents disabled)
