This commit takes several steps towards rendering text like we want to. The creation of the cairo surface and texture is moved to the backend (in GskVulkanRenderer). We add a mask shader that is used in the next text pipeline to use the texture as a mask, like cairo_mask_surface does. There is a separate color text pipeline that uses the already existing blend shaders to use the texture as a source, like cairo_paint does. The text node api is simplified to have just a single offset, which determines the left end of the text baseline, like all our other text drawing APIs.
