These formats require EXT_texture_norm16, which in turn needs OpenGL ES 3.1. The EXT_texture_norm16 extension does not support passing gl_internalformat = GL_RGBA to glTexImage2D, as can be done for formats available in OpenGL ES 2.0, so this commit adds a field to wlr_gles2_pixel_format to provide a more specific internalformat parameter to glTexImage2D.
