[SPARK-19944][SQL] Move SQLConf from sql/core to sql/catalyst
## What changes were proposed in this pull request?
This patch moves SQLConf from sql/core to sql/catalyst. To minimize the
changes, the patch used type alias to still keep CatalystConf (as a type alias)
and SimpleCatalystConf (as a concrete class that extends SQLConf).
Motivation for the change is that it is pretty weird to have SQLConf only
in sql/core and then we have to duplicate config options that impact
optimizer/analyzer in sql/catalyst using CatalystConf.
## How was this patch tested?
