3f29ea9144 [util] Add hb-shape --ned 
For not displaying extra data: no clusters, no advance. Just data pertaining
to where glyphs end up on the screen.

8c0d1916a4 Improve CGJ skipping logic 
Previously we made CGJ unskippable.  Now, if CGJ did NOT prevent
any reordering, allow skipping over it.  To make this work we
had to make changes to the Arabic mark reordering algorithm
implementation to renumber moved MCM marks.  See comments.

b68fba4dc8 [test] Use glyph ids instead of forcing ft funcs 
We were using ft funcs because these are CFF fonts, but we can avoid
glyph names instead and keep testing both ot and ft.

I simply removed the composite glyph and use the referenced simple
glyph directly.

70137e2b4b [test] We don’t care about glyph positions here 
Freetype and OT font functions give different positions for some glyphs
in this font (OT seems to be correct), but that is not what we are
interested in in this test.

81e2b9b8a9 Never skip over CGJ 
We might want to tweak this some more.  For now, never skipping over
it is better behavior than always skipping.

5d98de1f38 Tweak mark-base attachment 
Apparently a base glyph can also become an attached component of a
ligature if the ligature-forming lookup used IgnoreBase.  This was
being confused with a non-first component of a MultipleSubst and
hence not matched for mark-attachment.  Tweak test to fix.
