Initial pass on API stability guarantees This introduces -DWLR_USE_UNSTABLE and adds information regarding the stability status to all headers. I started with a conservative set of headers to mark as stable: - types/wlr_matrix.h - util/edges.h - util/log.h - util/region.h - xcursor.h

render/gles2: provide public API to access GL texture Prior to this commit, compositors needed to render the texture to an intermediate off-screen buffer using wlr_renderer APIs if they wanted to use a custom rendering path (e.g. render to a 3D scene). A new wlr_gles2_texture_get_attribs exposes the GL texture target and ID so that compositors can render wlr_textures with their own shaders. An example of a compositor doing so is available at [1].
