[PATCH v3 i-g-t 0/1] tests/intel/intel_sysfs_debugfs: Unify sysfs and debugfs testing

[Peter Senna Tschudin <peter.senna@linux.intel.com>]

The existing debugfs_test scans and reads relevant sysfs and debugfs
files, but it is limited to i915. Meanwhile, xe_debugfs.c provides
similar functionality for Xe but has two key gaps:
 - It lacks sysfs file testing.
 - It does not attempt to read all debugfs files.

This patch introduces intel_sysfs_debugfs, unifying both tests into a single
framework that ensures comprehensive coverage for both i915 and Xe.

Follow-up improvements

Once this patch is merged, I will submit a follow-up to:
 - Remove the redundant hwmon-basic test from debugfs_test, as
   intel_hwmon already provides full coverage for i915 and Xe.
 - Remove both debugfs_test and xe_debugfs.

The removal of existing tests impacts external test lists, requiring
updates that take time. By first addressing the test gap, we ensure
complete coverage while minimizing disruption. The follow-up series will
then focus on cleanup for improving long-term maintainability.

v3:
 - rename test to intel_sysfs_debugfs
 - fix copy paste error on commit message
 - expand Cc list

v2:
 - renamed xe-specific functions with the xe_ prefix
 - created two igt_subtest_groups: one for i915 and another for Xe
 - prefixed each test with either i915 or xe
