[type1,cff] Add FT_{Set,Get}_MM_WeightVector API calls.
For multiple master fonts, common usage (in Postscript) is to modify
the WeightVector of an existing font instance, this addition
supports that use.

Fix handing of `FT_Bool'.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.
Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.
*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.

Improve auto-hinter handling of bitmap fonts (#54681).
For bitmap fonts, `FT_Load_Glyph' should either return an error or
not set the format to `FT_GLYPH_FORMAT_OUTLINE'. However, in this
case `FT_Load_Glyph' calls into the auto-hinter which calls back
into `FT_Load_Glyph' with `FT_LOAD_NO_SCALE' in the flags, which
marks the glyph as `FT_GLYPH_FORMAT_OUTLINE' with an empty path
(even though it doesn't have any path). It appears that the
auto-hinter should not be called when the face doesn't have
outlines. The current test for using the auto-hinter in
`FT_Load_Glyph' checks if the driver supports scalable outlines, but
not if the face supports scalable outlines.
* src/base/ftobjs.c (FT_Load_Glyph): Directly check whether we have
scalable outlines.
