[display][coordinator] Remove async-watchdog.

The async-watchdog library provides a Watchdog class that
monitors the aliveness of a given async dispatcher by
posting periodical "update" tasks on the monitored dispatcher
and periodical "check" tasks on the Watchdog-owned loop.
In the display coordinator driver, it created an async::Loop
not managed by the driver framework, which is a discouraged
(and soon-to-be disallowed) behavior.

This change deletes the async-watchdog from the display
coordinator. Future changes will add other mechanisms to
avoid deadlocks within the display coordinator.

Test: no behavior change expected.
Test: no behavior change in the internal product on nelson.
Test: no behavior change in the internal product on VIM3.
