GLES translator - enable binding to multiple texture targets

support different binding to GL_TEXTURE_2D and GL_TEXTURE_CUBE_MAP
targets

create 2 default texture object, to be bound when BindTexture( ... ,0)
is called.
in order to do this, we must ensure their names are internal only, so the user can't
use these names by accident.
the object name manager local name is now 64 bit to allow generation of internal names
