bitbake: cooker: get extra information from recipe cache

The loaded cache modules may add extra attributes to
the recipecache, that will be populated by the cache
classes required by the UI. These attributes
will be used by the UI to display relevant information.

Adds cachefields cache class field to specify
for each cache class which attributes will be set
in the recipecache.

Adds code to automatically expand depends tree with the
fields exported by the extra cache class.

Fixes a cache field name in the HOB UI.
