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.

vulkan: Move push constants into their own header
...
This is the first step towards easing maintenance of the Vulkan shaders
by moving common code into headers.

- Rename from blit => blend
- Use instances
- Add clip versions

vulkan: Make the effect renderer take matrix + offset
...
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.

gsk: Add missing Mozilla copyright header
...
I stole one of their shader functions, and if I steal, I might as well
do it right.

vulkan: Fold clip into push constants

As a side effect, the clipping data is now available inside shaders.
Not that any shader would use them yet, but they could!

The color comes in instance data now, no need to abuse push constants
for it.

vulkan: Pass color rects in instance data

This way, we don't need push constants or per-vertex data, we can render
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.
