[BYOC] Update CUTLASS backend (SIMT support and codegen clean up)

[masahi]

The CUTLASS backend in Relay BYOC has been heavily refactored this month in the tlcpack/relax repo (as part of Relax BYOC effort). This PR brings the same change to apache/main and also adds SIMT fp32 support. All tests in test_cutlass.py pass.

Codegen clean up: tlc-pack/relax#442, tlc-pack/relax#451
SIMT fp32 support: tlc-pack/relax#448

Thank you @masahi

@tqchen as this isn't on the unity branch, in future could you allow others time to review in line with the code review guidelines?

Did this PR pass CI? I thought the upstream CI is broken with an Android problem.

[tqchen]

In this case it is a positive change overall so I think merging would benefit the community. I have also reviewed and confirmed the related logics. Happy to followup with necessary steps if there are more comments.

The android CI breakage is not relevant to the particular change.
