Do not consider the Evas_Vg API as BETA anymore

Summary:
It has been widely used for quite some time now.
Fixes T6889

Test Plan:
Manually built the evas-vg-simple.c and evas-vg-batman.c examples after
removing the manual define of EFL_BETA_API_SUPPORT and EFL_EO_API_SUPPORT
that they have at the top.
