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.
