Feature flags support in Chooser

A minimalistic replica of the SysUI feature flag infrastructure so the
app could both reuse some of the existing flag infrastructure (local
flag flipping) and have features controlled remotely (through
DeviceConfig).

A re-introduction of reverted ag/20796272 with the fixed
release build variant.

Bug: 262578843
Test: Manual tests with some injected debug code and local flag flipping
Test: Smoke tests both build variants
