[SPARK-13215] [SQL] remove fallback in codegen

Since we remove the configuration for codegen, we are heavily reply on codegen (also TungstenAggregate require the generated MutableProjection to update UnsafeRow), should remove the fallback, which could make user confusing, see the discussion in SPARK-13116.

Author: Davies Liu <davies@databricks.com>

Closes #11097 from davies/remove_fallback.
