display: Add support to HAL_PIXEL_FORMAT_NV21_ZSL format

Browse Source 
Add Support to HAL_PIXEL_FORMAT_NV21_ZSL format in gralloc for
camera capture usecase.
This support is required because, CPP module requires 64 byte
aligned width and height to resolve corruption in bottom/left edge
of the landscape/portrait buffer.
