[PATCH v2 i-g-t 0/7] Add xe_sriov_auto_provisioning tests

[Marcin Bernatowicz]

This patch series introduces several enhancements to the SR-IOV
provisioning and validation functionalities. The changes include
debugfs accessors, quota/spare attribute accessors, shared resource
provisionability checks, and helper functions for VF range validation.

Additionally, the xe_sriov_auto_provisioning tests validate the
following scenarios:
- Auto-provisioned resources are allocated by the PF driver in a fair
  manner.
- Auto-provisioned resources are released once VFs are disabled.
- Verify that ranges of auto-provisioned resources are exclusive.

v2:
- Update DEFINE_XE_SRIOV_PF_DEBUGFS_FUNC macro comment (Lukasz)
- Simplify range validation in test (Lukasz)
  (moved validation of provisioned ranges to library
  `xe_sriov_pf_debugfs_read_check_ranges`)
- Rename subtests for clarity (Lukasz)
- Add 'extended' command line option to enable dynamic subtests with
  arbitrary num_vfs
