[SYCL][CUDA] Refactor joint_matrix tests and remove legacy cuda extension (#8951)

The new joint_matrix portable extension has been live for a while now
and has made it into the latest release. In this PR I've removed the
legacy Cuda only version of the extension to avoid future confusion.
The Cuda joint_matrix e2e tests are also refactored so that they will
pass on any tensor cores supporting gpu. Previously sm_70, sm_72, and
sm_80 cases were included in the same test file. The target builtins
required compilation for sm_80 or above, and despite checks for compute
capability for each sm_xx test case within the main test file, since the
ptx does not jit if compiled for sm_80 but ran a lower compute
capability, e.g. sm_75, this led to an invalid binary error in such a
case. Now the tests are split into files referencing the minimum compute
capability for test cases included in the file, meaning that the test
cases will run and pass on any tensor cores supporting gpu.

`get_wi_data()` is deprecated in the cuda backend and we can remove this
support before the next release and remove corresponding test cases from
joint_matrix_apply_cuda.hpp.
