Rename BootImageModule to BootclasspathFragmentModule

Also renames files, tests, module types in a similar fashion.

There are still some references to image and boot image. They are kept
for the following reasons:
* image_name - this is the name of an ART boot image, i.e. the
  collection of .art/.oat/.vdex files.
* BootImageInfo - again this is related to the ART boot image.
* .../art_boot_images/... paths - ditto.
