evas/gl_x11 : Add multiple_buffer member in native surface x11 type union.

Summary:
If native surface is multiple buffer pixmap such as named pixmap, Evas should recreate eglImage everyframe.
Because DDK get the buffer ID once at eglImageCreate time.
So if internal buffer ID is changed, should recreate eglImage.

Test Plan: Wearable Tizen.
