[roll] Roll fuchsia [time][alarms] Integration fixes for the wake alarm manager

- Introduces a GetProperties() FIDL API - this is needed by the connection
  probing in Starnix.
- Temporary CancelSync() FIDL API for Starnix migration.
- Factors out the `alarms` crate from `timekeeper`, so that it can be
  reused in test fixtures.
- Adds a `wake-alarms` test-only components which implements wake alarms
  management, but none of the UTC management of Timekeeper. This helps
  wake-alarms specific integration tests (mostly the hermetic ones) be
  more focused, and have less unrelated setup.
