unittests target for which libsync doesn't provide the

DrmAtomicStateManager.cpp is the only file which depends

flag, such that any method which would depend on libsync
is now stubbed when it is unavailable.

The IStats service provides an interface for reporting metrics from
vendor processes through the IStats::reportVendorAtom interface.
The type and ordering of the data in a VendorAtom are determined by a
proto definition which is typically OEM-specific. The code to construct
the VendorAtom is generated from the proto definition.
Add a soong config variable in the DRMHWC config namespace to enable the
atom reporting. Currently there is only one such implementation.
atom_reporter: Set this to configure OEM-specific atom reporting.
With the config variable omitted, reporting will be disabled and a stub
implementation is used, ensuring no build or runtime dependency or usage
of the IStats service.

CompositionStats struct is a copy of HwcDisplay::Stats and is extracted
from HwcDisplay as a prestep for supporting stats reporting beyond
dumpsys.
CompositionStatsProvider interface can be implemented by a class that
will poll all displays and return a display->CompositionStats map for
the cumulative stats for each display.
CompositionStatsTracker is a helper class that tracks the state of the
last queried stats and calculates the delta between the last stats and
the currently pulled stats. A Callback function can be passed into the
Report function which will be called for each display, with the
cumulative and delta stats as arguments.

Check the "Present Not Reliable" property to determine if the capability
PRESENT_FENCE_IS_NOT_RELIABLE should be enabled or not.
The virtio gpu module sends frames to the host as fast as possible and
does not emulate "real display timing". Devices using the virtio gpu
module (for example, the virtual Android device Cuttlefish) should set
the following property to "true" to enable the capability:
ro.vendor.hwc.drm.present_not_reliable.enabled
For example, in an Android BoardConfig.mk:
PRODUCT_VENDOR_PROPERTIES += \

We use too much dup() system calls for present fence propagating.
Also when propagating acquire fence we use additional logic for
skipping such propagation for the validate/test cycle.
Both issues can be solved by introducing SharedFd, which will track
reference count of fd object.
After that the UniqueFd is used very rarely and can be simplified by
wrapping it into std::unique_ptr without caring too much of adding
an extra malloc/free operation.

1. Move BlendMode, ColorSpace, SampleRange fields to the struct BufferInfo,
allowing extraction of the data from native_handle using Metadata@4 API.
Use it when data from HWC2 API can't be used (Currently it's a BlendMode
case for CLIENT layer)
2. Rename DrmHwcLayer to LayerData and move it to compositor/ directory.
(I was confused in the past because of similarity of names DrmHwcLayer
vs HwcLayer, so this step should meke it easier for newcomers to
understand the code)
3. Allow clonning of the LayerData to propagate it through the composition
pipeline. Thus LayerData can be used by both HwcLayer to track state
and by the compositor.
