Auto merge of #25814 - szeged:mmatyas__webgl_fns_framebuf_texlayer, r=jdm
Add support for WebGL2 FramebufferTextureLayer Adds support for `FramebufferTextureLayer` WebGL2 call. See: https://www.khronos.org/registry/webgl/specs/latest/2.0/#3.7.4 <!-- Please describe your changes on the following line: --> Depends on #25798. cc @jdm @zakorgy --- <!-- Thank you for contributing to Servo!
