drm/amd/display: Wire probe commit path into dc_update_state

[Why]
The dc_update_state commit interface and the dc_probe object model existed
but were not connected: there was no path to validate, commit, and program
a probe through the update pipeline, nor to read the result back. The
measurement waits on OTG frame edges and must not block fast updates.

[How]
- Move the per-commit scratch off dc_stream_state onto a dc-owned pool;
  acquire at init, release on cleanup or prepare failure, serialized by the
  DM global lock every commit path already holds.
- dc_update_state drives stream commits, probe-only commits, or both through
  one staged init/prepare/execute/cleanup loop with a null-arg guard. prepare
  releases the scratch slot on failure; cleanup releases it on success.
- Probe prepare installs the absolute probe set in place; execute calls the
  perfmon programming hook in the unlocked window and latches results.
- Add resource_validate_probe_set, a context-free achievability check shared
  by dc_validate_global_state (full update) and probe prepare (probe-only).
- dc_state_get_status gains a probe status class with a probe filter and a
  by-type mapping; dc_validation_set gains probes/probe_count. Drop the dead
  actual_* fields from struct dc_qos_info.
