Also introduce new supported RAW image file formats, PEF and SRW.
RAW image file formats are not defined in PTP 1.2 specification except
for DNG. They are mostly built on top of TIFF or TIFF/EP. (Fuji's RAF
is the exception).
In this CL, image file formats are classified newly as below:
DNG: dng
TIFF: cr2, nrw, arw, rw2, orf, pef, srw
TIFF/EP: nef
Unknown Image Formats(FORMAT_DEFINED): wbmap, webp, raf
I referred to the following documents for defining MTP formats of RAW
images:

Because not all MTP devices support getPartialObject, we need to check
supported operation of MTP devices. The CL adds operationsSupported
field to MtpDeviceInfo class.
