This fix a GL_INVALID_VALUE error on startup due to 0.0f max line width.
Also moves the max anisotropy filter to the sampler creation.
This reduces code fragmentation.
This should not cause any problem since the depth test is required
in order to draw to the depth buffer and this is not altered by
this change.
To be on the safe side, we still restor the mask after altering it.
This is quite embarassing... it was returning the base instance instead of
the correct vao. No wonder that it was causing crash and at most drawing
issues.
This replace `GPU_clear()` by `GPU_clear_color()` and `GPU_clear_depth()`.
Since we always set the clear value before clearing, it is unecessary
to track the clear color state.
Moreover, it makes it clearer what we clear the framebuffer to.
This changes the state of occlusion queries quite a bit. Now scissors is
explicitely disabled and we enabled color write.
I still don't understand why we now need this. This patch is just trial and
error on an affected setup. Note that on the same computer, renderdoc
was not able to capture the regression (the regression did not manifest
during capture).

This is in preparation of vulkan backend. We move all opengl
functionnalities behind an abstract class.
This also cleansup the "dynamic" ubo create and rename it to
`GPU_uniformbuf_from_list()`
Contains, no functional change.
Part of T68990 Vulkan support.
This follows the GPU module naming of other buffers.
We pass name to distinguish each GPUUniformBuf in debug mode.
Also remove DRW_uniform_buffer interface.
This make use of the GLStateStack functions for:
- `GPU_blend()`
- `GPU_blend_set_func()`
- `GPU_blend_set_func_separate()`
The goal is to unify them using an explicit state setting.
This will remove the need to use obscure blend functions
Now error printing only display the line related to the error.
We also put char marker if present.
Example:
```
-- Shader Compilation Errors : MAMaterial --
10414 | node_fresnel(, facingnormal, viewposition, tmp34);
| ^
| error: syntax error, unexpected ',', expecting ')'
