The third coordinate of the 2D sampling code is only used for 2D array
textures, so we don't compute a filter factor. This used to be taken
advantage of by passing the filter factor of the second coordinate to
the addressing method for the third coordinate, and ensuring that the
addressing mode of this component was ADDRESSING_LAYER even for non-
array textures.

Instead of relying on this brittle hack, just specify a third filter
factor. Now that we elide materialization of single-block variables,
this doesn't take any stack space and is zero overhead to the backend.

This matches what's in the manually managed vcxproj for the two modules.

to those platforms. Note that these are guarded with #ifdef _WIN32

Previously only the texture pointer was passed to the sampling routine,
containing some sampler data which is (still) wrongly assumed to come
from a combined image-view and sampler descriptor. This change will
allow splitting them up correctly.

Also refactor getImageSampler to not start the Reactor function
generation, moving it entirely into emitSamplerFunction so that the
latter only has to be passed the pointers to the descriptor state that
will affect the code that's generated.

Name all the parameters according to their actual type.

Clamp sampler LOD on construction so we don't have to deal with it any
more later.
