This is the first step of moving the create infos
back inside shader sources.
All info files are now treated as source files.
However, they are not considered in the include tree
yet. This will come in another following PR.
Each shader source file now generate a `.info` file
containing only the create info declarations.
This renames all info files so that they do not
conflict with their previous versions that were
copied (non-generated).

Do this only when applicable.
This allow better compile time checking in Shader C++ compilation.
Moreover, this allows to have `constexpr` in shared code between
C++ and GLSL.
After investigation the `const` keyword in GLSL has the same
semantic than C/C++.

This unify the C++ and GLSL codebase style.
The GLSL types are still in the backend compatibility
layers to support python shaders. However, the C++
shader compilation layer doesn't have them to enforce
correct type usage.
Note that this is going to break pretty much all PRs
in flight that targets shader code.

They are actually already some literals with the `f` suffix
that are in our shader codebase and we never had problem in
the past 5 years (or even 8 years).
So I think it is safe to do and improves convergence of codestyles.
