[sfnt] Reduce footprint if WOFF and WOFF2 support is not needed.
Based on a patch from metarutaiga (MR !106). The gist of this commit is
that it doesn't make sense to support WOFF without compression (which would
be only possible in WOFF 1.0 anyway).
* src/sfnt/sfobjs.c (sfnt_open_font): Guard WOFF code with
`FT_CONFIG_OPTION_USE_ZLIB` block.
Guard WOFF2 code with `FT_CONFIG_OPTION_USE_BROTLI` block.
* src/sfnt/sfwoff.c, src/sfnt/sfwoff.h: Guard files with
`FT_CONFIG_OPTION_USE_ZLIB` blocks, not parts of the code.
* src/sfnt/sfwoff2.c, src/sfnt/sfwoff2.h, src/sfnt/woff2tags.c,
src/sfnt/woff2tags.h: Guard files with `FT_CONFIG_OPTION_USE_BROTLI` blocks,

[mm] Tolerate missing Blend dictionary entries
In a Multiple Master font, the Blend dictionary must contain valid
Private, FontInfo, and FontBBox. The current code will error if any of
these are present and invalid, but will not error and will provide
uninitialized data if the Blend dictionary exists but does not contain
one of these entries. This change reverts to the older behavior of
treating any missing entries as containing all zero data and not
returning an error.
In the future it may be best to keep track of when these are actually
initialized and error if they are not.

[mm] Delay setting blend weight and design position.
Previously the `blend->weight_vector`, `blend->default_weight_vector`,
and `blend->design_pos` were set early to allocated but uninitialized
memory under the assumption that the memory would eventually be
initialized. However, it is possible that some of the required
keywords may not actually be present, leaving the memory uninitialized.
This is different from a present but invalid table, which would produce
an error.

[sfnt] Delay setting gasp ranges and count until computed.
Previously, the gasp.numRanges was set and gasp.gaspRanges was
allocated and assigned before a possible early exit if the frame could
not be entered. It is also possible that the gaspRanges allocation
could fail but the numRanges still be set to non-zero. In such cases
an error would be returned, but the face would have a gasp in an
inconsistent state which may still be accessed.

[smooth] Reduce shift in multiply-shift optimization.
* src/smooth/ftgrays.c (FT_UDIVPREP, FT_UDIV): Reduce shift.
Smaller shifts that keep the division operands of FT_UDIVPREP within
32 bits result in slightly faster divisions, which is noticeable in
the overall performance. The loss of precision is tolerable until the
divisors (the components dx and dy) approach 32 - PIXEL_BITS. With
PIXEL_BITS = 8, this corresponds to 65,000 pixels or the bitmap size
that we refuse to render anyway.
Using `ftbench -p -s60 -t5 -bc timesi.ttf`,
Before: 8.52 us/op
After: 8.32 us/op

[truetype] New function to skip the randomization tag.
* src/truetype/ttobjs.c (tt_skip_pdffont_random_tag):
New function to skip the randomization tag in the names of the
fonts embedded in a PDF. It is used by tt_check_trickyness_family(),
to keep from mistaking "DLC" in the randomization tag as a
tricky font name. See discussion in:
https://lists.nongnu.org/archive/html/freetype-devel/2021-02/msg00002.html
For technical detail about the randomization tag, please find
PDF Reference 5.5.3 "Font Subsets". Thanks to Justyna Wawrzynska
for pointing out the issue caused by the randomization tag.
