TextureTools: reverse landfill direction only if it makes sense.

Instead of piling up a mountain if the other end is a ditch. Results in
better packing in most cases, but in one doesn't, so also adding an
option to disable this.

The docs image is now slightly more leveled, one pixel lower.

TextureTools: reduce AtlasBenchmark iterations.

It takes too long in debug mode, causing timeouts on the Windows CI due
to older MSVC having truly amazing virtually unmatched debug build
performance.

TextureTools: new landfill atlas packer.

Just the dumbest possible idea I had, and it compares surprisingly well
in both efficiency (~comparable to stb_rect_pack) and speed
(significantly faster than stb_rect_pack with tons of tiny images,
slower with larger ones -- would probably need to SIMD Math::max() and
such, haha). It's the very first implementation without any additional
improvements I have in mind, so it'll likely improve further.

Includes a benchmark with a bunch of "datasets" extracted from both
fonts and large glTF models. The stb_rect_pack file isn't commited as
it's not useful apart from this single benchmark, put it to
AtlasTestFiles/ and recompile.
