Revise IAllocator and IMapper to reduce IPC and to support gralloc0
devices.
Specifically, IAllocator is trimmed down to have essentially only
allocate(BufferDescriptor descriptor, uint32_t count)
generates (Error error,
uint32_t stride,
vec<handle> buffers);
The ability to allocate buffers with shared backing store is
removed. ProducerUsage and ConsumerUsage are moved to the
graphics.common package and are merged and renamed to BufferUsage.
BufferUsage's bits follow gralloc0.
IMapper gains
typedef vec<uint32_t> BufferDescriptor;
createDescriptor(BufferDescriptorInfo descriptorInfo)
generates (Error error,
BufferDescriptor descriptor);
where BufferDescriptor is an implementation-defined blob. lockFlex
is replaced by lockYCbCr. All getters are removed.
Reference counting with retain/release is replaced by
importBuffer/freeBuffer.
Most if not all gralloc1 features are not used by the runtime yet.
There is also not too much test written for them. As such, they
tend to behave differently between implementations and cannot be
used reliably.

Otherwise some bits will be set incorrectly.
Also move device@1.0 to use ProducerUsageFlags instead of ProducerUsage,
and add a compatibility workaround to set the gralloc0 HW_CAMERA_ZSL flags
when ConsumerUsage::CAMERA is passed in.
Test: Camera CTS passes, updated VTS tests pass
