Review of indexes on CatalogItemAsset and ecfVersionAsset

Description

• ecfVersionAsset non clustered index IDX_ecfVersionAsset_WorkId can be removed as it is already covered by the clustered index.

• CatalogItemAsset clustered index should changed to be CatalogEntryId first, as it's expected to have better cardinality, and that would make the non clustered index IX_CatalogItemAsset_EntryId obsolete.

• IX_CatalogItemAsset_NodeId should include GroupName and SortOrder, so it no longer needs to do key look up.
