Extend storage-api to expose FilterContext

To enable row-level filtering at the ORC level ORC-577, or as an extension ProDecode MapJoin HIVE-22731 we need a common context class that will hold all the needed information for the filter.

I propose this class to be part of the storage-api – similar to VectorizedRowBatch class and hold the information below:

• A boolean variable showing if the filter is enabled
• A int array storing the row Ids that are actually selected (passing the filter)
• An int variable storing the the number or rows that passed the filter
