Treat bad values passed to --images as a fatal error

If an option is passed to --images that is either a non-existent path or
a folder with no images matching the supported types, assume this is
an error and exit, so they can supply a valid path instead.

Share code between DM and nanobench in SkCommonFlags.

nanobench now behaves more like DM - it will check a directory for
images that match the supported extensions.

Only consider image paths ending in RAW suffixes as images if
SK_CODE_DECODES_RAW is defined. This prevents us from seeing failure
to decode errors on platforms that cannot decode it.
