LibSoftGPU: Test for 1.f equality in determining the scale factor
...
We are still not doing the right thing here, but using `<=` instead of
`<` at least gets rid of artifacts in Grim Fandango.

LibSoftGPU: Choose correct texture filter based on scale factor
...
Previously the test determining whether to use texture maginifaction or
texture minification was reversed. This commit fixes the test and also
provides an early out of the sampler in case of texture magnification
since magnification does not make use of mipmaps.

LibSoftGPU: Use bitwise and instead of modulus operator for POT textures
...
Where possible the sampler will wrap texture coordinates using a bitwise
and instead of a modulus. This speeds up the calculation quite a bit.

LibSoftGPU: Mark wrap_clamp as [[maybe_unused]]
...
This was breaking the fuzzer build becaues the function is not used
if the `CLAMP_DEPRECATED_BEHAVIOR` constexpr is not `true` during
compile time.

LibSoftGPU: Clamp to edge instead of border
...
According to the Khronos FAQ on texture edge sampling, the `GL_CLAMP`
option was never implemented in hardware and as such, it was
deprecated. A lot of applications and games depend on `GL_CLAMP` not
really meaning `GL_CLAMP` but `GL_CLAMP_TO_EDGE`, so we introduce an
option to toggle this behavior at compile-time.
