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).

a1a5570e97 Replace the previous OpenGL loader with a glad-generated 3.3 one 
The main advantage of switching to glad from glLoadGen is that, apart
from being actively maintained, it supports a customizable entrypoint
loader function, which makes it possible to also support OpenGL ES.

254582aa35 OpenGL: Fix state tracking in situations with reused object handles 
If an OpenGL object is created, bound to a binding using the state
tracker, and then destroyed, a newly created object can be assigned the
same numeric handle by OpenGL. However, even though it is a new object,
and thus needs to be bound to the binding again, the state tracker
compared the current and previous handles and concluded that no change
needed to be made, leading to failure to bind objects in certain cases.

This manifested as broken text in VVVVVV, which this commit fixes along
with similar texturing problems in other games.
