0287a004 - improve NTuple show and cleanup code for Vararg and NTuple type parameter construction (#51244)

improve NTuple show and cleanup code for Vararg and NTuple type parameter construction (#51244) Various simplifications and improvements from investigating #51228. Improves the logic for showing of NTuple to handle constant lengths. Improves the logic for showing NTuple of bound length (e.g. NTuple itself). Also makes a choice to avoid showing non-types as NTuple, but instead try to write them out, to make it more visually obvious when the parameters have been swapped. --------- Co-authored-by: Jameson Nash <vtjnash@gmail.com>
