[sfnt] Improve handling of invalid SFNT table entries (#45987).
This patch fixes weaknesses in function `tt_face_load_font_dir'.
- It incorrectly assumed that valid tables are always at the
beginning. As a consequence, some valid tables after invalid
entries (which are ignored) were never seen.
- Duplicate table entries (this is, having the same tag) were not
rejected.
- The number of valid tables was sometimes too large, leading to
access of invalid tables.
* src/sfnt/ttload.c (check_table_dir): Add argument to return number
of valid tables.
Add another tracing message.
(tt_face_load_font_dir): Only allocate table array for valid
entries as returned by `check_table_dir'.
Reject duplicate tables and adjust number of valid tables
accordingly.

Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification
https://color-emoji.googlecode.com/git/specification/v1.html
which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively). The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images. If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.
Note that color bitmaps are converted to grayscale if client didn't
ask for color.

[sfnt] Fix broken pointer overflow checks.
Many compilers such as gcc and clang optimize away pointer overflow
checks `p + n < p', because pointer overflow is undefined behavior.
Use a safe form `n > p_limit - p' instead.
Also avoid possible integer overflow issues, for example, using
`num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2'
given a large `num_glyphs'.
