Add a mapping from HAL RAW formats to the direct equivalent of libcamera
formats. With this change it is possible to capture RAW images as long
as the hardware can deliver frames in a format that is native to the
HAL.

More work is needed to deal with unpacked 8, 10 and 12 RAW formats as
they don't directly map to a native HAL format. Nor do they belong in
the RAW_OPAQUE category as the content format is generic and not
uncommonly supported by hardware.
