[sdf] Skip neighbor comparison for pixels near edges.
If the distance of the current pixel to the edge is less than or equal
to 0.5, skip further neighbor comparisons to avoid unnecessary
calculations. When the `USE_SQUARED_DISTANCES` macro is defined,
compare to 0.25 instead.
* src/sdf/ftbsdf.c (compare_neighbor): Add early return for pixels
close to edges to avoid unnecessary neighbor checks.

Use unsigned point and contour indexing in `FT_Outline`.
This doubles the number or allowed points, see
https://github.com/harfbuzz/harfbuzz/issues/4752
Although it is hardly practical to use more than 32767 points,
other font engines seem to support it.
* docs/CHANGES: Announce it.

Fix invalid memory access in `bsdf` rasterizer.
Do not generate SDF from bitmap if the `FT_GLYPH_OWN_BITMAP` flag is not
set. In some cases the bitmap buffer is freed but still points to a valid
address; to handle those cases check the flag before accessing the memory.
* src/sdf/ftsdfrend.c (ft_bsdf_render): Handle the above case.
Also, return an error message if the bitmap's rows/pitch is invalid,
otherwise `slot->buffer` might be assigned to some invalid memory location.
(ft_sdf_render): Same as above.
Plus, move the outline back to original state after rasterization and not if
any error occurs.

[sdf] Use 8 bits for final SDF output instead of 16bits.
Since 8-bits is enough to represent SDF data we no longer require
16-bits for this purpose. Also, we now normalize the output data
to use the entire 8-bit range efficiently. For example: if we use
3.5 format with a spread of 1 we basically only use the starting
5-bits. By normalizing we can use the entire 8-bit range.
* include/freetype/freetype.h (FT_Render_Mode): Updated description
for `FT_RENDER_MODE_SDF` regarding this change.
* include/freetype/ftimage.h (FT_Pixel_Mode): Removed
`FT_PIXEL_MODE_GRAY16` since no longer required.
* include/freetype/fttypes.h (FT_F6Dot10): Removed since no longer
required.
* src/sdf/ftsdfrend.c (ft_sdf_render, ft_bsdf_render): Allocate 8-bit
bitmap instead of 16-bit buffer.
* src/sdf/ftsdfcommon.h (map_fixed_to_sdf): Added function to convert
16.16 distance value to our desired format.
* src/sdf/ftsdf.c (sdf_generate_with_overlaps,
sdf_generate_bounding_box): Use the new `map_fixed_to_sdf` function
and also use 8-bit output buffer.
* src/sdf/ftbsdf.c (finalize_sdf): Output to a 8-bit buffer instead
