a couple of compiler warnings with gcc 11 on freetype 2.10.4

Hi Werner,

There are two new warnings from building 2.10.4 on current fedora. One is 
likely from the newer gcc 11:


src/base/ftlcdfil.c:360:42: warning: argument 2 of type ‘FT_Vector *’ {aka 
‘struct FT_Vector_ *’} declared as a pointer [-Warray-parameter=]
  360 |                              FT_Vector*  sub )
      |                              ~~~~~~~~~~~~^~~
include/freetype/ftlcdfil.h:314:42: note: previously declared as an array 
‘FT_Vector[3]’ {aka ‘struct FT_Vector_[3]’}
  314 |                              FT_Vector   sub[3] );
      |                              ~~~~~~~~~~~~^~~~~~


The other seems to be due to newer harfbuzz:

src/autofit/afshaper.c:135:5: warning: ‘hb_ot_tags_from_script’ is deprecated: 
Use 'hb_ot_tags_from_script_and_language' instead [-Wdeprecated-declarations]
  135 |     hb_ot_tags_from_script( script,
      |     ^~~~~~~~~~~~~~~~~~~~~~
/usr/include/harfbuzz/hb-ot-deprecated.h:63:1: note: declared here
   63 | hb_ot_tags_from_script (hb_script_t  script,
      | ^~~~~~~~~~~~~~~~~~~~~~


I think the first one is probably trivial to fix (the header has to stay, so 
the function itself probably need to be modified); the latter is perhaps a bit 
more troublesome if one wants to preserve compatibility with older harfbuzz.
