[idd] hdr: complete HDR display and cursor metadata
...
Publish BT.2020 chromaticities in the virtual monitor EDID so
Windows receives a valid HDR colour volume.
Extend cursor messages with their IddCx SDR white level and an
explicit visibility-valid flag. Consumers can then calibrate cursors
without treating colour-transform-only messages as cursor hides.

[idd/client] apply the Windows display color transform
...
Honor the IddCx 3x4 XYZ matrix and post-transfer LUT in the IDD
conversion pipeline. Carry transform changes to the client so EGL applies
the same calibration to hardware cursors, and invalidate the full frame
whenever calibration changes.

[idd] cancel stale swap chain assignments

Invalidate in-progress swap chain setup when IddCx unassigns the
monitor, and serialize replacement assignments so workers are
never started on abandoned handles.
Also initialize all worker dependencies before starting the processing
thread and treat teardown during SetDevice as normal cancellation.

[idd] serialize monitor replugs with swap chain teardown
...
Keep the replug lifecycle gated until the old swap chain has drained and
released its pending frame, and the replacement swap chain is fully
initialized. Coalesce additional requests into a follow-up replug to
prevent overlapping topology changes and IddCx release-frame timeout
bugchecks.

[idd] avoid release frame timeouts during replug
...
Drop frames when the LGMP queue is full instead of blocking
while holding an IddCx surface. Always finish every
acquired frame, including duplicate frame numbers, so
replug teardown cannot trigger the release-frame watchdog.

[idd] keep the generated EDID immutable
...
Generate the EDID once during adapter initialization and update only the
live mode list when resolutions change.
Changing the EDID during a monitor replug causes Windows to identify it
as a different monitor, losing the existing display configuration.
Reusing the original EDID preserves the monitor identity while still
allowing dynamic modes to be advertised through IddCx.

clients from waiting on work that has not yet been queued. Track the
last published buffer separately for safe subscriber resends and handle
