Corrected F2I None mode to RoundEven.

shader_ir: Clean texture management code

nvdisp_disp0: change drawing message log level from Warning to Trace

gl_rasterizer_cache: Fixup texture view parameters

These parameters were declared as constants and passed to glTextureView
but then they were removed on a rabase. This addresses that mistake.

This is a leftover from the early yuzu days.
We shouldn't log every time when we are drawing by default, so let's change the log level to Trace.

This was originally included because texture operations returned a vec4.
These operations now return a single float and the F4 prefix doesn't
mean anything.

Previous code relied on GLSL parameter order (something that's always
ill-formed on an IR design). This approach passes spatial coordiantes
through operation nodes and array and depth compare values in the the
texture metadata. It still contains an "extra" vector containing generic
nodes for bias and component index (for example) which is still a bit
ill-formed but it should be better than the previous approach.

shader/track: Add a more permissive global memory tracking

- This is a blit, use the blit registers.

i965 (and probably all mesa drivers) require GL_PROGRAM_SEPARABLE when using
glProgramBinary. This is probably required by the standard but it's ignored by
permisive proprietary drivers.
