More work on text nodes 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.

vulkan: Drop GskVulkanPipelineLayout We already move the descriptor set layout out of it, so we can just as well keep the pipeline layouts in the render object as well, and get rid of this extra object. Update all callers.

vulkan: Better glyph cache api Move the glyph caching api to something that can support using multiple textures. We now split the text render ops into multiple ops for different textures, and make each op render just a substring of the text node's glyph string.

gsk: Scale glyphs in the glyph cache Pass a scale factor when caching glyphs or looking them up in the cache. The glyphs in the cache are rendered with subpixel precision determined by the scale. Update all callers to pass a scale factor according to the window scale. This lets us render crisp glyphs on hidpi systems.
