Added custom error message when trying to assign constraint type to generic type parameter (#30394)

Browse Source 
* Added custom error message when trying to assign constraint type to generic type parameter

Fixes #29049.

This also adds the new message in chained error messages. `typeParameterDiamond4.errors.txt` shows it appearing twice in the "diamond" scenario. I can't tell if this severely increased amount of nested messages is good or bad...?

* Updated diagnostic message per suggestion

* Align formatting with local custom
