[Patch Request] drm/xe: Implement Wa_22016122933 to fix GuC TLB invalidation ack stalls on Arrow Lake

### Pre-flight checklist

- [x] I have searched existing issues/PRs and this has not been requested before.
- [x] I have read the [Contributing Guidelines](https://github.com/CachyOS/linux-cachyos/blob/master/CONTRIBUTING.md).

### Request type

- [x] New patch / patchset inclusion
- [ ] Kernel config change (enable/disable option)
- [ ] New kernel variant
- [ ] Scheduler tuning / addition
- [ ] Compiler / LTO / PGO optimization
- [ ] Security hardening
- [x] Driver or hardware enablement
- [x] #1039

### Summary
Requesting the inclusion of the v3 patch series for `drm/xe` implementing `Wa_22016122933`.

On Arrow Lake-S (ARL) systems using the `xe` driver, media workloads and video acceleration trigger frequent GuC TLB invalidation ack stall timeouts and platform freezes (`*ERROR* TLB invalidation fence timeout`). This occurs because the CPU reads stale cache lines from the G2H CTB on the standalone media GT.

### Hardware Details
- **System:** Lenovo ThinkCentre M70t Gen 6 (Mobo: 3376)
- **CPU:** Intel Core Ultra 5 235 (Arrow Lake-S, 14 cores)
- **GPU:** Intel Arrow Lake-S [Intel Graphics] (PCI ID: `00:02.0`, Device ID: `7d67`, rev 06)
- **Driver:** `xe` (boot parameter: `i915.force_probe=!7d67 xe.force_probe=7d67`)
- **Desktop Environment:** KDE Plasma 6.7.5 (Wayland), Mesa 26.2.2-arch3.2

### Patch References
- **Mailing list thread:** https://mid.mail-archive.com/dri-devel%40lists.freedesktop.org/msg630443.html
- **Message-ID:** `20260824140748.54974-1-talesam@gmail.com`
- **GitLab tracking issue:** https://gitlab.freedesktop.org/drm/xe/kernel/-/work_items/8678

### Testing & Verification
Tested against `linux-cachyos` (7.2.4):
- All 3 patches in the v3 series applied cleanly to the CachyOS kernel tree without merge conflicts.
- Completely resolves the GuC TLB invalidation timeouts and desktop/media freezes.

### Motivation / use case

Prevents platform freezes and GPU driver crashes on Arrow Lake (ARL) systems using the `xe` driver.

Currently, media workloads and hardware video acceleration trigger frequent GuC TLB invalidation ack stall timeouts (`*ERROR* TLB invalidation fence timeout`). This happens because the CPU reads stale cache lines from the G2H CTB on the standalone media GT.

Implementing `Wa_22016122933` resolves the caching erratum, completely eliminating the timeouts and restoring stability under Wayland and media workloads.

Tested on `linux-cachyos` (7.2.4-1):
- All 3 patches in the v3 series applied cleanly to the CachyOS kernel tree without merge conflicts.
- Hardware: Intel Core Ultra 5 235 (Arrow Lake-S) on Lenovo ThinkCentre M70t Gen 6 (Device ID `7d67`).

Result: Zero TLB invalidation timeouts and zero media freezes after applying the patch.

### Additional context

The series consists of 3 patches:
1. `drm/xe: Capture devcoredump on TLB invalidation timeout`
2. `drm/xe: Log when a timed out TLB invalidation ack finally arrives`
3. `drm/xe: Implement Wa_22016122933`

It carries no extra external dependencies and builds cleanly with default CachyOS flags.
