[CK] Disable compilation of problematic bwd weight conv
instances for gfx90a (#6343)

## Motivation
Due to compiler version update, there are test failures in the test
suite `test_grouped_convnd_bwd_weight` when running on `gfx90a`. There
are four failing tests for FP16/BF16 that arise from a single kernel
instance. As the problem is in the current `develop` branch, the test
failures are blocking any PR merges into `develop`. An example of a
failed CI runs is here:
[http://micimaster.amd.com/blue/organizations/jenkins/rocm-libraries-folder%2FComposable%20Kernel/detail/develop/558/pipeline/](http://micimaster.amd.com/blue/organizations/jenkins/rocm-libraries-folder%2FComposable%20Kernel/detail/develop/558/pipeline/).
The underlying compiler problem is potentially the same as described in
#6342 as tests are passing for clang compiler version 20.0 and failing
for clang compiler version 22.0.
## Technical Details
This PR disables the compilation of the problematic bwd weight conv
instance for `gfx90a` by adding a new CMake flag `CK_USE_GFX90A` that
allows us to detect when we are compiling for `gfx90a`. Using the new
CMake flag, compilation of instance
`DeviceGroupedConvBwdWeight_Xdl_CShuffleV3<64, 128, 32, 32, Default, 8,
4, 1, 8, 8, 8, 8, 1, 1, 2>` is disabled for `gfx90a`.
