[Impeller] Implement framebuffer fetch support for OpenGLES. (#46585)

https://github.com/flutter/flutter/issues/120223 for OpenGLES. Checks for support of the framebuffer fetch extension: https://registry.khronos.org/OpenGL/extensions/EXT/EXT_shader_framebuffer_fetch.txt . This is supported on a Pixel 6 at least, we should double check the distribution of the extension.
