[PATCH v5 3/4] lib/igt_core: Enable automatic platform filtering in subtest execution

[<vitaly.prosyak@amd.com>]

From: Vitaly Prosyak <vitaly.prosyak@amd.com>

Hook platform filtering into __igt_run_subtest() so tests automatically
skip subtests based on platform rules without requiring manual
igt_platform_require() calls in each subtest.

This means tests only need to call platform_filter_init() once in their
igt_fixture, and all subtests are automatically checked against the
platform filtering rules before execution.

Example test code:
  igt_fixture {
      amd_platform_filter_init(&gpu_info);
  }

  igt_subtest(my-test) {
      // Automatic skip if platform rules match - no manual call needed!
      test_code();
  }

v3 changes:
 - This is now patch 4/6 (was 5/7 in v2) due to squashing of patches 1+2
   per Kamil Konieczny's review feedback
 - No code changes from v2
