--LPS-76488-- upgraded the AssetEntries_AssetCategories table to AssetEntryAssetCategoryRel, and all new AssetEntry to AssetCategory relationships are stored as entries in that new table, but AssetEntryAssetCategoryRelLocalService does not expose the same accessors that AssetEntryLocalService expose publicly.

Steps to reproduce / testing done:
1. Created a new category in Control Panel>Categories>Vocabulary>Topic
2. Create a new web content with that category assigned
3. Performed this in 7.0 and 7.1
4. Checked AssetEntries_AssetCategories and AssetEntryAssetCategoryRel tables in 7.0 vs. 7.1 
Results of steps / testing:
7.0 category is saved to AssetEntries_AssetCategories
7.1 category is saved to AssetEntryAssetCategoryRel
Errors/logs:
n/a

Expected Result: 
There are new methods available in the AssetEntryAssetCategoryRelService to retrieve data about AssetEntryAssetCategoryRel entries that replace the old AssetEntry and AssetCategory service methods, as the AssetEntries_AssetCategories table is no longer used.

Actual Result:
There are no new methods in the AssetEntryAssetCategoryRelService available to retrieve data about AssetEntryAssetCategoryRel entries.
