build: Move Vulkan shader handling to its own directory
...
Spooky action at a distance is not really allowed in Meson, so the rules
to generate the SPV files should go in their own directory.

vulkan: Compute right size for outset shadow
...
We were emitting the box and not the shadow box as the rectangle. So we
didn't draw any shadows. Oops.

vulkan: Generate clip shaders from same source
...
Instead of having 3 different shaders for the different clipping
versions, just have one shader and use a preprocessor define to use
different clip functions.
That preprocessor define is set in the Makefile.
Also use foo.frag and foo.vert as the file extensions instead of using
foo.frag.glsl and foo.vert.glsl, as that's what glslc suggests as
extension.

Implement clipping the same way as in the last commit for the
fragment shaders.

vulkan: Add a clip.frag.glsl include
...
This include is supposed to handle clipping for the different clipping
methods.
So far, we only use it in the rounded rect cases.

vulkan: Add push constants to fragment shader
...
That way we don't need to move the clip rounded rect manually through
the vertex shader into the fragment shader but can just look at the push
constants.
Simplifies shaders a lot.

This is the first step towards easing maintenance of the Vulkan shaders
by moving common code into headers.

This is in preparation for the new color matrix node.
I don't think keeping support for a separate opacity shader is worth it.

vulkan: Handle opacity nodes

Well, "handle" them actually. We still draw the node's child using
Cairo, but we apply the opacity manually now.

vulkan: Handle linear gradients
...
Note: We interpolate premultiplied colors as per the CSS spec. This i
different from Cairo, which interpolates unpremultiplied.
So in testcases with translucent gradients, it's actually Cairo that is
wrong.

I stole one of their shader functions, and if I steal, I might as well

colored rectangles completely via instance data.

gsk: Loads of work on Vulkan backend

We can now upload vertices.
And we use this to draw a yellow background. Which is clearly superior
to not drawing anything.
Also, we have shaders now. If you modify them, you need glslc installed
so they can be recompiled into Spir-V bytecode.
