Remove random_fullrank_matrix_distinc_singular_value (#68183)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/68183
We do so in favour of

correctly for them to work with the PR that tests noncontig inputs
latter in this stack.
We also heavily simplified the generation of samples for the SVD, as it was
fairly convoluted and it was not generating the inputs correclty for
the noncontiguous test.
To do the transition, we also needed to fix the following issue, as it was popping
up in the tests:
