bitmap: Adds cogl_android_bitmap_new_from_asset()

This adds some android specific api for creating a CoglBitmap from an
Android asset.

As part of the work it also seemed like a good time to change the
internal bitmap constructors to take an explicit CoglContext argument
and so the public cogl_bitmap_new_from_file() api was also changed
accordingly to take a CoglContext pointer as the first argument.

(cherry picked from commit 099d6d1b505b55bbd09c50d081deb41ab5764e19)

  Since we aren't able to break APIs on the 1.12 branch this cherry-pick
  skips the change to cogl_bitmap_new_from_file()
