  Fix state of `FT_Face' for buggy `gvar' tables (#57923).
  
  By resetting the blend as implemented with this commit fonts with
  invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
  `tt_set_mm_blend' and failing, but the font was invalid anyway and
  we want to keep seeing the failure in `tt_set_mm_blend'.
  
  * src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of
  offset array once.
  Allocate arrays after `FT_FRAME_ENTER' (extra check before
  allocating and avoid needing to free array later if error entering
  frame).
  Always call `FT_FRAME_EXIT'.
  Consistently set counts immediately after array initialized.
  Reset the blend (particularly `blend->glyphoffsets') on failure.
