[SPARK-12950] [SQL] Improve lookup of BytesToBytesMap in aggregate
This PR improve the lookup of BytesToBytesMap by:
1. Generate code for calculate the hash code of grouping keys.
2. Do not use MemoryLocation, fetch the baseObject and offset for key and value directly (remove the indirection).
Author: Davies Liu <davies@databricks.com>
Closes #11010 from davies/gen_map.
