Update the compile-time warp size constant for ROCm 7.0

[fwyzard]

PR description:

ROCm 7.0 no longer defines the warp size as a compile-time constant.
Work around it using preprocessor macros.

PR validation:

Code compiles with ROCm 7.0.

If this PR is a backport please specify the original PR and why you need to backport that PR. If this PR will be backported please specify to which release cycle the backport is meant for:

Unlikely to be backported to 15.1.x, unless we need ROCm 7.0 in that release branch.

I guess this is working as intended since all tests pass.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @ftenchini, @sextonkennedy, @mandrenguyen (and backports should be raised in the release meeting by the corresponding L2)
