Read embedded dcp profile from raw files

Browse Source 
raw files, usually dng files, can provide a dcp profile by providing the
related tags.

This patch will make the "Use embedded" options in the color management
panel selectable if the source raw file embeds a dcp profile.
In this case the DCP panel will be enabled like when reading an external
dcp profile.

Additional changes:

* Rename "Use embedded, if possible" to just "Use embedded" since the
option is already disabled when no embedded profile is found.
* Update the "Use embedded" options tooltip as it's now not related to
  only non raw images.
