[roll] Roll fuchsia [power] Add unique ID for wake leases in Inspect.

The ActivityGovernor FIDL API doesn't require unique naming
for wake leases. This creates confusion in Inspect logs if
multiple wake leases have the same name.

This CL adds a unique ID that follows the same wake lease
throughout its lifecycle. The unique ID increases monotonically.
No two leases (whether wake or application activity) should have
the same ID (within a reasonable amount of time due to overflow of
u64).
