[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.
