Invoke yagl_gles2_context_prepare_framebuffer in glClear for GLESv2/GLESv3submit/tizen/20211224.014123accepted/tizen/unified/20211227.122832

- glClear can be used to clear entire framebuffer. Therefore invoke
  yagl_gles2_context_prepare_framebuffer in glClear for GLESv2/GLESv3
  to write back clear result if the fb is binded with texture that
  targets from an eglimage.
