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).

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.

VSE timeline widget drawing is done in "timeline space" (x: frames,
y: channels), but that can have precision issues at large frames,
when "pixel size features" (outlines, borders) need to get evaluated
inside a shader.
This can lead to inconsistent border sizes between neighboring strips,
e.g. sometimes it would be 2 pixels, but sometiems 3 pixels. I've seen
this mostly happen when frames get into 100'000+ range.
To address this, switch timeline widget drawing to be in window pixel
space. This avoids the issue since coordinates to draw the strip
widgets become "up to several thousand" range, not arbitrarily large.

Previously selected strips in VSE timeline were drawing their outline
1px outside of the strip boundaries. This makes outlines of the strips
overlap each other when neighboring strips are selected.
Now the selected outline is fully within regular strip shape.

PR #122576 added rounded corners to VSE timeline strips, but they were not
"snapped" to pixel grid so the outline that is normally 1px was sometimes
falling in between pixels and was blurred out.
Fix by rounding all SDF related coordinates inside the shader to the pixel
grid.

VSE timeline strips now have rounded corners. Strip corner rounding radius is
4, 6 or 8px depending on strip height (if strip is too narrow to fit
rounding, then rounding is turned off).
This is achieved with a dedicated GPU shader for drawing most of VSE
strip widget, that it could do proper rounded corner masking.
