Implement new API to modify MIME groups by adding/removing MIME types

MIME groups can now be modified via PackageManager.
MIME group modification will affect intent-filters
that were declared with that |mimeGroup| in manifest
in the same way, as if intent-filter was initially
declared with |mimeType| attributes that correspond to
MIME types in MIME group

Preferred activities will be handled in the next CL
