On platforms (like PVC) that do not support walker mid-thread
preemption, running tests in forked threads can lead to inconsistent
states due to igt_skip being called mid-execution. Made changes to
perform kernel preemption check at the beginning of each subtests.
If the GPU version does not support the required features, the
test is skipped gracefully, ensuring consistent behavior across
different platforms.

TODO: Add the kernel for PVC

v2: Fixed review comments to move the compatibility check
    into the igt_fixture. [Priyanka]

v3: Added check for thread group preemption and WMTP.
    Added enum flags for preemption type as per review . [Zbigniew]

v4: Added check for preempt inside __run_intel_compute_kernel_preempt
    Refactored the code.  [priyanka]

v5: Refactor for finding the kernel and out of bound check. [Zbigniew]

v6: Added NULL Check for kernel. [Zbigniew]
