[M85 Migration][Rendering] Force gpu acceleration

Chromium-efl port does not support s/w mode. So we need to set h/w
mode before creating elm_window. To do this, make constructor function
which is called at library loading time and set "ELM_ACCEL=hw" here.
If not, native app which does not call elm_config_accel_preference_set()
function will fail to execute.
