* fix: skip integrated GPU in IGCL enumeration to prevent duplicate hardware entries
IGCL's ctlEnumerateDevices returns all Intel graphics devices including
the integrated GPU, but IntelDiscreteGpu was created for every device
without filtering. This caused the iGPU to appear twice: once from the
IGCL path (as IntelDiscreteGpu) and once from the D3D path (as
IntelIntegratedGpu), with overlapping sensors.
Check the CTL_ADAPTER_PROPERTIES_FLAG_INTEGRATED flag on each device's
graphics_adapter_properties and skip integrated adapters, since they are
already handled by IntelIntegratedGpu via D3D enumeration.

* feat: add IGCL-based telemetry sensors for Intel integrated GPUs
Use Intel Graphics Control Library (IGCL) to expose temperature, clock
frequency, and voltage sensors for the integrated GPU via the safe
user-mode ctlPowerTelemetryGet API. Each sensor is only activated if
the driver reports it as supported, so this degrades gracefully on
hardware/drivers that don't expose specific telemetry items.
This mirrors the approach already used by IntelDiscreteGpu, bringing
parity between discrete and integrated Intel GPU monitoring.
Depends on: fix/intel-igpu-deduplication
