After investigating the crash logs it looked like the macro
unrolling wasn't working on Windows systems with these GPUs.

Macro unrolling was changed in order to cross compile to Metal and
in the future to Vulkan. The macro unrolling in OpenGL can be removed
by using a different naming scema.

This PR removes the macro unrolling by changing the generated GLSL
code:

Before

layout(std140) uniform _probe_block
{
  ProbeBlock probe_block;
};

After

layout(std140) uniform probe_block
{
  ProbeBlock _probe_block;
};

Some tweaks had to be done to the Eevee-shaders to make sure that
the macro unrolling is done correctly and could be compiled using
legacy opengl drivers.

Fix: #106278
Fix: #106555
(and others)

**TODO**

- [ ] Let users validate if this fixes the issue, or that more work is
  required.
- [ ] Check if pre OpenGL 4.3 is still working. Those platforms don't
  support explicit binding.

Needs testing, but it looks complete to me.

Note that this change breaks MacOS/AMD (eevee doesn't crash, but doesn't show anything) so this needs to be investigated before continuing)
