Mark FT_Renderer_Class::raster_class as pointer to const
The `FT_DEFINE_RASTER_FUNCS` macro declares a `const FT_Raster_Funcs`.
The address of the definition is taken and assigned to
`FT_Renderer_Class::raster_class` which is currently `FT_Raster_Funcs*`.
Until recently the `const` was cast away and with the removal of the
cast there are now warnings about dropping this `const`. Instead of
adding back the casts, make `FT_Renderer_Class::raster_class` a pointer
to const, as is done with pointers in other interfaces.
* include/freetype/ftrender.h (FT_Renderer_Class_): mark `raster_class`
as const.

[gzip] Don't compile internal zlib development files when using system zlib.
`src/gzip/rules.mk` compiles the internal zlib sources even when using the
zlib development files provided by a host system. If the internal zlib
development files are not present, FreeType fails to build from source.
This patch ensures the internal zlib development files are only
prerequisites when not using zlib development files on a host system.
* src/gzip/rules.mk (GZIP_DRV_SRCS): Define conditionally.

* src/truetype/ttgload.c (TT_Hint_Glyph): More mostly cosmetic update.
This is a follow-up to commit 49c74ac02, which creates a new local variable
"exec = loader->exec", and shortening a lot of "loader->exec". This commit
does two more such changes missed in that first commit.

[cff] Make blend operator work with floats in private dicts.
The CFF2 blend operator takes N default values and corresponding
sets of deltas and pushes N values specific to a designspace
location. CFF has a floating point numeric type and the FreeType
blending code was not converting those into its internal 16.16
Fixed type format.
Fixes #1243.
* src/cff/cffparse.c (do_fixed): Handle floating point numbers.
Also fix scaling overflow check for integer-to-fixed conversion.
* src/cff/cffload.c (cff_blend_doBlend): Updated.

[woff2] Remove sfnt size guess check
In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value
is now just a hint and a conforming implementation must not reject
otherwise valid data if the `totalSfntSize` turns out not to be exact.
* src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed
woff2 data would fit in the sfnt size guess.

* vms_make.com: Provide separate library compiled with C++.
Some types on OpenVMS x86_64 (for example, `long') have different sizes
depending on whether compiled with either C or C++. In particular,
X-Windows applications crash if linked with the C++ version.
This patch makes `vms_make.com` create a second version of the FreeType
library compiled with C++ if OpenVMS is running on the x86_64 platform.

Avoid overflow in COLR bounds checks.
The values read into `base_glyphs_offset_v1` and `layer_offset_v1` may
be in the range 0xFFFFFFFD-0xFFFFFFFF. On systems where `unsigned long`
is 32 bits adding 4 to such values will wrap and pass bounds checks but
accessing values at such offsets will be out of bounds.
On the other hand `table_size` has already been tested to be at least
`COLRV1_HEADER_SIZE` (34) so it is safe to subtract 4 from it.
* src/sfnt/ttcolr.c (tt_face_load_colr): subtract 4 from `table_size`
instead of adding 4 to font data offsets in bounds checks
