SoftGPU: Add the secondary color on the portable triangle path
...
Without SSE or NEON, triangle pixels got the secondary color in place of
the primary one plus it, so lit triangles came out black. It showed as
the "unexplained" known failures on riscv64 and loongarch64, and broke
the new gpu/lighting/shademap there. Reproduced on arm64 by building
without NEON.

softgpu: Force alpha test when it could skip blend.
...
Blending is slow, and often games do effects like smoke, sun, etc. that
has a lot of zero alpha in them. Many games do this with alpha testing
off, which is cheap compared to blending.

softgpu: Force alpha test off in more scenarios.
...
Since we're already checking the CLUT, we can tell if it doesn't contain
zero alpha, in which case a != 0 test will never fail. This is actually
pretty common, even when texture alpha is not always FF.
