Use OFN as the intermediate format more widely.

OFN is already the default intermediate format for import modules and
components. This commit makes it the format for more files, including:

* the $(EDIT_PREPROCESSED) file;
* the $(SRCMERGED) file (strictly speaking this is not necessary: the
  `$(SRCMERGED)` variable points to a file with a `.ofn` extension, so
  ROBOT already writes that file in OFN format;
* remotely sourced components;
* the merged mirror file.
