Set the reflection name for ShaderCollection::Item to "ShaderCollectionItem" so it doesn't show up as just "Item" in Script Canvas. Note that this change was made in main only, not in the 1.0 branch, to de-risk the beta branch.
Testing:
Ran the repro steps for the bug, and ran the ShaderManagementConsole's GenerateShaderVariantListForMaterials.py script successfully.

LYN-2905 Script Canvas: Saving a graph that contains an Item Variable crashes the Editor
Added a check for m_shaderAsset.IsReady() before trying to use the asset data. Also added a check before calling BlockUntilLoadComplete() to prevent reporting an error message unnecessarily.
