[SPARK-13923] Implement SessionCatalog
## What changes were proposed in this pull request?
As part of the effort to merge `SQLContext` and `HiveContext`, this patch
implements an internal catalog called `SessionCatalog` that handles temporary
functions and tables and delegates metastore operations to `ExternalCatalog`.
Currently, this is still dead code, but in the future it will be part of
`SessionState` and will replace `o.a.s.sql.catalyst.analysis.Catalog`.
A recent patch #11573 parses Hive commands ourselves in Spark, but still
passes the entire query text to Hive. In a future patch, we will use
`SessionCatalog` to implement the parsed commands.
## How was this patch tested?
700+ lines of tests in `SessionCatalogSuite`.
