Raise exception when transformation not supported for echelon_form()

[HenryWu2101]

#37480
This is a preliminary fix for the issue mentioned, where it raises exception whenever echelon_form() does not support argument "transformation=True".
The list of all matrix class that has its own echelon_form():
matrix2
matrix_cyclo_dense
matrix_integer_dense
matrix_mpolynomial_dense
matrix_rational_dense
matrix_rational_sparse

The list of matrix class that does not support transformation and thus modified to raise exception:
matrix_cyclo_dense
matrix_mpolynomial_dense.pyx
matrix_rational_dense.pyx
matrix_rational_sparse.pyx

We should for the moment use this fix for the issue so that we don't have the "ignore user input" phenomenon, but keep the issue for future.

@vneiger @maxale For the latest commit, I have changed the "raise exception" approach to "warnings", which I feel would be more aligned with the previous behavior, when this time it gives a result for echelon_form() and with a message suggesting a workaroud. This I think is a better solution for a temporary fix.

Thanks for the work. What about other classes, e.g. matrix_mod2_dense, matrix_modn_dense, matrix_polynomial_dense, ... ? I do not see where they are handled in your changes. Apart from that, I tried your code on the modified methods, and the warning idea looks good to me.
