Clément Foucault fe213f80a4 GPU: Shader: Make info files generated 
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).
