Fix for LYN-4594: [Atom][EMFX] Loading a saved level with entity and an actor component causes the editor to freeze. (DCO fixup) (#1878)

Browse Source 
* Queue shader loads and register with the dynamic draw context after the shader is loaded to avoid a deadlock when there are multiple scenes processing at the same time.

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

* Fixed AzCore case in AtomFont.h and two other files I found while searching

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

* Switched to a utility that will both get the assetId and create the Asset, without calling GetAsset explicitely

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

* Fixing typos in error message
