Tommy Walton aef1f01de2 Expose OnModelReady to behavior context for hydra automation (#4331) 
* Expose OnModelReady to behavior context for hydra automation

Signed-off-by: amzn-tommy <waltont@amazon.com>

* Adding assets used by the hydra test to Atom/TestData

Signed-off-by: amzn-tommy <waltont@amazon.com>

* Attempt to fix line ending

Signed-off-by: amzn-tommy <waltont@amazon.com>

* Moving behavior context for mesh notification bus to the component controller

Signed-off-by: amzn-tommy <waltont@amazon.com>

* Changed the AssetManager DispatchEvents function to continously pump the
AssetBus of queued functions until empty.

This replicates the old behavior of the EBusQueuePolicy::Execute
function that would continue to execute functions if new ones were added
during the execution of the current queue.

Split the TestFixture class from the AssetHandler and EBus handler for the DynamicSliceInstanceSpawnerTests and
PrefabInstanceSpawnerTest.
This avoids the AssetMananager destructor from deleting the test fixture
if the call to UnregisterHandler is ever removed. This also allows the
memory allocators to get online earlier.

* Removing an incorrect [[maybe_unused]]
