vulkan: Split texture caching code Instead of having one function that gets the image for the texture and uploads it if it doesn't exist yet, make it 2 functions: One to get the texture if it exists. One to assign an uploaded image to the texture. This way, we can potentially do the upload ourselves.

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/vulkan/glyphcache: Rework glyphs The current implementation of the glyph cache deals with atlases by padding them with 1 pixel at the beginning, at the end, and between each glyph. That's cool and all, however, there's a very subtle problem with this approach: the contents of the atlas are garbage, so this padding is filled with garbage memory! Rework the Vulkan glyph cache to draw each and every glyph in a surface that has 1 pixel border of padding around it. Ensure the surface is completely black by drawing a rectangle before handing it to Pango to draw the glyph. Update tx and ty to pick the texture position adjusted to the 1 pixel padding. The atlas now starts at position (0, 0), since each glyph individually contains its own padding. To improve legibility, add a PADDING define and use it everywhere.

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.
