* Add Intel Arc VRAM sensors support
- Implement BDF-based device matching for Intel discrete GPUs
- Add VRAM sensors (total, used, free, load percentage)
- Use D3D device enumeration with fallback logic
- Enable Windows-specific VRAM monitoring for Intel Arc GPUs
- Fix device identification to distinguish between multiple identical GPUs
Resolves issue where both Intel Arc GPUs showed identical VRAM values.
Now each GPU displays unique, accurate memory usage statistics.
* Add defensive validation to GetBdfFromDeviceIdentifier
- Add null/empty check for deviceIdentifier parameter
- Return false explicitly when LastIndexOf('#') returns -1
- Add DEVPROPTYPE.DEVPROP_TYPE_UINT32 validation after property queries
- Use sizeof(uint) instead of hardcoded 4 for buffer sizes
- Apply PCI spec bit masks (5-bit device, 3-bit function)
- Add bus range validation (0-255)
* Revert to Windows DEVPKEY_Device_Address spec masks
Use 0xFFFF masks as per Windows documentation instead of PCI spec
bit widths. The Windows API uses full 16-bit fields for device and
function numbers.
* Update IntelDiscreteGpu.cs
* Update NativeMethods.txt

- Add GPU Memory Total, Used, Free sensors (SmallData type, in MB)
- Add GPU Memory load sensor (percentage)
- Add GPU Memory Read/Write bandwidth sensors (Throughput type, in B/s)
- Use D3DDisplayDevice API to query VRAM usage via Windows kernel
- Match Intel discrete GPUs using PCI vendor/device IDs
- Include fallback detection for Intel GPUs if initial matching fails
- Bandwidth sensors read from Intel GCL telemetry with unit conversion
ADL finds multiple logical gpus, this commit avoids multiple
unneeded initializations of AmdGpu class. The main control is moved to
AmdGpuGroup and the ADL_* calls are updated to ADL2_*, using the
context. Adapters using PMlog should be initialized only if sensors are
detected, adapters that pmlog is not enabled or doesn't work, should
fallback previous logic.
* Refactor ADL sensors update
- Check support for each sensor, on OD8 and new PMLog.
- Exclude cards before Vega10 from using PMLog
- Better validation for individual sensor support (for now asic-power/board-power)
- Validate pmlog struct using the lastUpdate, there are situations the
sensors values are corrupted, maybe because something blocking the pointer access to
the struct, but this needs to be verified.
* Update AmdGpu.cs

* Add ADL pmlog support, fix metrics on newer gpus
Newer GPUs needs this to show performance metrics properly. Sample rate
is hard coded (1000ms).
* Clean up
