Introduce EmptyStateUiHelper (& initial tests)

Based on prototype work in ag/24516421, this CL introduces a new
component to handle the empty-state UI implementation details that had
previously been implemented in `MultiProfilePagerAdapter`, since those
details significantly clutter the implementation of that adapter's
other responsibilities.

As in ag/24516421 patchset #4, this just sets up the boilerplate and
kicks off with some "low-hanging-fruit" operations. Follow-up CLs will
continue migrating these responsibilities as in ag/24516421 (except
with more incremental testing).

Bug: 302311217
Test: IntentResolverUnitTests, CtsSharesheetDeviceTest
