sdm/hwc/gralloc: Move fb_id lifecycle to DAL

--Move fb_id creation/deletion from gralloc to DAL and make it per
cycle
--Make Gralloc/HWC/SDM structures independent of libdrmutils
and fb_id / gemhandles
--Pass BufferAllocator pointer to Display* and HWDevice*
--Add new GetBufferLayout API to BufferAllocator that can be called
by DAL before creating fb_id
