Drew Davenport 129d12f38a drm_hwcomposer: Report composition stats as vendor atoms 
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.
