021cb0bced renderer_opengl: Use textures for fragment shader LUTs instead of UBOs. 
- Gets us LUT interpolation for free.
- Some older Intel GPU drivers did not support the big UBOs needed to store the LUTs.

05356543d9 OpenGL: Downgrade GL_DEBUG_SEVERITY_NOTIFICATION to Debug logging level 
The nVidia driver is *extremely* spammy on this category, sending a
message on every buffer or texture upload, slowing down the emulator and
making the log useless.

195fedccf0 VideoCore: Unify interface to OpenGL and SW rasterizers 
This removes explicit checks sprinkled all over the codebase to instead
just have the SW rasterizer expose an implementation with no-ops for
most operations.

e9c209ccc8 PICA: Properly emulate 1-stage delay in the combiner buffer 
This was discovered and verified by @fincs. The tev combiner buffer
actually lags behind by one stage, meaning stage 1 reads the initial
color, stage 2 reads stage 0's output, and so on.

Fixes character portraits in Fire Emblem: Awakening and world textures
in Zelda: ALBW. Closes #1140.

0735630744 Use regular uniform location 
The support for GL_ARB_explicit_uniform_location is not that good
(53% according to http://feedback.wildfiregames.com/report/opengl/feature/GL_ARB_explicit_uniform_location).

This fix the shader compilation on Intel HD 4000 (#1222).
