Subject: Generate OpExecutionMode PointMode for tessellation shaders (#7662)

* Generate "OpExecutionMode PointMode" for tessellation shaders instead of the incorrect geometry and mesh shader specific "OpExecutionMode OutputPoints".

* Add a test case verifying the OpExecutionMode is correct.

Fixes #7660
