caa94f923e drm_hwcomposer: Update Content Protection prop on Uevents
Kernel sends Uevents when Content Protection changes its value
from Desired -> Enabled on HDCP enabling or when it changes
from Enabled->Desired on HDCP termination.

This patch updates the content protection property value
on Uevents to capture the change in its state by the kernel.

81071ba3ce Restore cached DrmKmsPlan reuse
This change restores behavior where the DrmKmsPlan cached during
ValidateStagedComposition is reused during Present. That behavior
was disabled in a prior change due to a bug where the client
layer could become stale if it were updated between the validate
and present steps, which is now resolved by this change.

48f056ff82 Track stats per unique composition attributes
This change adds a new CompositionAttributes struct which
tracks information about a given composition as it is
validated and subsequently presented.

Previously CompositionStats were tracked as totals for each
display. This change splits the stats according to the
CompositionAttributes for each presented composition.

This change only affects the reporting behavior of
CompositionStatsTracker. The stats logged by DumpState are
totaled so as to not be affected.

9a76e062b6 Move EdidWrapper from DrmConnector to HwcDisplay
The EdidWrapper lifecycle was previously managed by DrmConnector,
meaning the EDID parser was initialized when the connector was created.
This approach fails for physical connectors where a display is not
attached at boot, as no EDID blob is available to parse.

When a display was subsequently hot-plugged, the system would fall back
to a generic EdidWrapper. This provided incorrect or default display
properties to userspace, causing critical bugs such as:

  * Incorrect DPI calculations, leading to improperly scaled UI in
    Android.
  * Inability to detect HDR capabilities or supported color modes.

This change moves the ownership and lifecycle management of the
EdidWrapper to HwcDisplay. By creating the parser only when a display is
actually connected, we ensure that the correct EDID is always parsed,
making hot-plug functionality work as intended.

a51a43422d drm_hwcomposer: Use cached validated composition
This change adds caching to save the most recently
validated composition. The cached value is used where
appropriate to avoid recalculating the DrmKmsPlan or
the CompositionTypeMap from ValidateDisplay again in
PresentDisplay. The cached ValidatedComposition
replaces the previously cached DrmKmsPlan, preserving
the lifecycle management requirements.

99f677a2ea drm_hwcomposer: Manage current_plan_ lifecycle
This change refactors the lifecycle management of
HwcDisplay::current_plan_. The purpose of the current_plan_
is to keep plane bindings in memory between calling
ValidateDisplay() and PresentDisplay(). This ensures that
bound planes will not be stolen by other CRTCs in the
interim, which could cause a validated composition to
become invalid before it can be presented.

The current_plan_ is intended to fulfill the contract
prescribed by the documentation of
Backend::ValidatedComposition::composition_plan, which
requires the plan to not be destructed until the
composition is committed.

Prior to this change, the lifetime of current_plan_ was
extraneous. Rather than being released after
PresentDisplay(), it was being unnecessarily held until
the next ValidateDisplay(). This would have the
unintended effect of holding the plane bindings after
the composition has been committed, which would prevent
other CRTCs from using the shared planes during that time.

This change updates the management of current_plan_,
still satisfying the Backend's contract, but releasing it
once it is appropriate to do so.

2432cb0dfa drm_hwcomposer: Update FlatteningController behavior
Under the previous behavior, NewFrame both updated the internal state
tracking to indicate that the scene is not idle, as well as returning a
bool to indicate whether the scene should be flattened or not.
ShouldFlatten was not being used, and would return `true` during the
interval between the refresh callback being triggered and the next
NewFrame, which would be in response to the refresh callback. Subsequent
calls to ShouldFlatten would return `false` even though the scene
remains idle.

This commit updates NewFrame to only update the internal state. Callers
should call ShouldFlatten to check whether the controller has detected
that the scene should be flattened.

After the callback is triggered, ShouldFlatten returns true. It will
continue to return true after the first NewFrame, which would be in
response to the refresh callback. Subsequent NewFrame calls will reset
the idle detection.

ac727c57ae drm_hwcomposer: Fix used_plane state tracking
Ensure that the next frame's list of used_planes is correct. The list of
used planes for the new frame is initialized to the previous frame's
list of planes when creating the AtomicRequest. If there is a
composition as a part of this request, the list should be cleared before
creating the new composition, since the list will be re-populated.

Neglecting to clear this left planes on the list when they shouldn't
have been, or the same plane multiple times. This led to some spurious
commit and validation failures on single display configurations, but on
multiple display configurations also resulted in highly visible stuttering.
