Since it's not possible to update 300+ shaders manually and automation was possible, I thought that I'd take the honor and create a script that's able to automatically convert all of the shaders to be cross-compatible with Vulkan. And change the graphic pack versions to version 4 of course.
Also, the script has some nifty testing code which compiled every shader as OpenGL and Vulkan, but for that see the details that I've written below.
**Here's the script that I've made to do all of this. No manual edits were needed:**

Both had some weird stuff going on which the Vulkan converter couldn't successfully compile. Also, the presets in the anti-aliasing might be nice, but they are not even used in the shader 🤔.
Since I wanted to make sure that I didn't broke the shaders after converting the shaders to Vulkan, we need to check if all the shaders weren't broken. Since we're talking about like 400 shaders checking all of them is pretty much impossible and even then,
So, the obvious solution was to automate the checking. Not as simple as you'd think, because in 300 of our shaders we use preset variables which without replacing the value like Cemu does, will make the shader error regardless. So I also implemented some functionality that would read the preset values and types out of the rules.txt file and replace them in the shaders using that information. And then we use Khronos' glslang to compile the shaders, using both OpenGL and Vulkan.
The result was that glslang found quite a few errors in some of the shaders, which I fixed in this commit. I'm considering adding this rules.txt parsing and automated shader compilation testing to the build process.
Also, I fixed Clarity's name and description since Monochromia isn't available anymore and Xenoblade's resolution pack had a lot of weird blank lines before their #version declaration, which my converter didn't like.
Resolves https://github.com/slashiee/cemu_graphic_packs/pull/400 since this is a self-made addition since I noticed several other things that I'd like to have been tweaked, plus it wasn't symmetrical and had weird names for the added presets.
Reverts everything except main viewports. Seems most below 480
eventually gets used and breaks objects later in game. 1280x720 1 -> 5
stable so far.. But keeping an eye on that one.
As of Cemu 1.15.12b, the textureSrcResolution (textureSrc_Resolution not texture_SrcResolution) uniform used by internal/external resize shaders still gives the native resolution of the game even when a resolution gfx pack is active.
We can just ask for texture resolution ourselves in the shaders as a workaround.
Also removed the version indicator in Windwaker's contrasty file since any updates to that number would remove all the configuration set by the user for that pack.
