drm/amd/display: Introduce dc_probe public object model

[Why]
Performance measurement needs to commit through the same update entry
point as planes and streams, with DM working against an abstraction of
what to measure rather than the hardware block that performs it.

[How]
Add dc_probe.h defining dc_probe_type (the measurable quantity),
dc_probe_target_state (not measuring / measuring / measured),
dc_probe_scope (global only, per-stream/plane deferred), and
dc_probe_state (an inline descriptor with copy semantics, no refcount).
dc_state carries the committed set as probes[MAX_PROBES] plus
probe_count. dc_state_update carries dc_probe_updates as the desired
absolute set that DC diffs against the committed set.
