Handle VK_FORMAT_G10X6_B10X6R10X6_2PLANE_420_UNORM_3PACK16 sampling

As
https://swiftshader-review.googlesource.com/c/SwiftShader/+/63748
was incomplete and introduced some failures as seen in
https://swiftshader-review.googlesource.com/c/SwiftShader/+/63628.

Updates `SamplerCore::sampleTexel()` to handle both 8-bit and 10-bit
formats by reading the 8-bit or 10-bit buffers values without 8.8
packing (e.g. packing the 8-bit raw `u` value from the buffer into
both the high 8-bits and low 8-bits of `U`) and by using more
generic range expansion (as opposed to the hardcoded constants for
8-bit).
