[NI] Remove failing codegen tests and add similar diagnostic one

These tests were added for suspend-conversions, it worked only
 with new inference, but implementation was incorrect and had other
 bugs, which were fixed in 1ac25259.
 Support of suspend-conversions will be addressed later with a different
 implementation (#KT-30703)
