df3bbbb7ad varLib: use hhea.ascent and head.unitsPerEM for phantom pts when vmtx missing

52ec934a02 varLib: use vmtx to compute phantom pts; fix sign of bottomSideY 
when 'vmtx' is present in a font, use that to compute the third and fourth 'phantom points'.
When not present, we use the glyph bbox yMax and yMin coords.

NOTE that previously the bottomSideY was incorrectly set to -glyph.yMin (with a minus sign).
However, the minus is not needed when we use the bbox.
Positive vertical advance grows towards negative Y axis.

* Revert "load_masters: actually assign font attributes"

This reverts commit ef1d4cd02d1e46f5dac3914f547a6e4275cf3077, which caused a
crash in `interpolate_layout()` when `deepcopy`ing OTFs.

Amend code and tests while I work on a real fix.

[varLib] allow loading masters from TTX files as well 
in a designspace document, the sources' filename attribute can now contain
a relative path to a .TTX file for that master, in addition to .TTF or .UFO
(the latter, resolved through a master_finder callable as before).

varLib: use addMultilingualName method to support localized axes 'labelname' 
now that addMultilingualName method also adds mac names by default, we can use it in

The language identifiers are expected to be minimized, i.e. not contain default script/region
subtags -- until we implement the minimizeSubtags algorithm from ICU/CLDR:

0586c06199 [varLib subset CFF2] Set PrivateDict nominal and default WidthX to None 
@bedhad
Address issues raised in #1403

I do think setting the dummy CFF2 PrivateDict nominalWidthX and defaultWidthX to None, which leads to the charstring.width also being None,  is a good idea. I originally set them to 0, which produces a charstring width of 0, in order to avoid problems with logic that assumes that the field is good for math. However, I now think that it is better to find errors around charstring type assumptions earlier than later.

 "drop_hints()" is actually not wrong - I did look at this when making the changes. For CFF2 charstrings, self.width is always equal to self.private.defaultWidthX, so the width is never inserted. This is because in psCharstrings.py::T2WidthExtractor.popallWidth(), the test "evenOdd ^ (len(args) % 2)" is alway False.  Left to myself, I would not change this code. If the CFF2 charstring is correct, there is not a problem. if the CFF2 charstring is not correct, then both in drop_hints() and in T2WidthExtractor.popallWidth(), the logic will stack dump. I did add asserts, but am not totally sure it is worth the extra calls.
