vbo: Ignore PRIMITIVE_RESTART_FIXED_INDEX for glDrawArrays().
The derived _PrimitiveRestart enable flag combines the PrimitiveRestart
and PrimitiveRestartFixedIndex enable flags. However, DrawArrays is not
supposed to do FixedIndex restart:
From the OpenGL 4.3 Core specification, section 10.3.5 (page 302):
"If PRIMITIVE_RESTART_FIXED_INDEX is enabled, primitive restart is not
performed for array elements transferred by any drawing command not
taking a type parameter, including all of the *Draw* commands other
than *DrawElements*."
The OpenGL ES 3.0 specification agrees by omission:
"When DrawElements, DrawElementsInstanced, or DrawRangeElements
transfers a set of generic attribute array elements to the GL..."
Notably, DrawArrays is not included in the list of draw calls that
take PRIMITIVE_RESTART_FIXED_INDEX into consideration.
