[SPARK-18519][SQL] map type can not be used in EqualTo
## What changes were proposed in this pull request?
Technically map type is not orderable, but can be used in equality comparison. However, due to the limitation of the current implementation, map type can't be used in equality comparison so that it can't be join key or grouping key.
This PR makes this limitation explicit, to avoid wrong result.
## How was this patch tested?
updated tests.

Closes #15956 from cloud-fan/map-type.
