mesa: Set DriverFlags.NewArray together with vbo...recalculate_inputs.

Both mean something very similar and are set at the same time now.
For that vbo module to be set from core mesa, implement a public vbo
module method to set that flag. In the longer term the flag should
vanish in favor of a driver flag of the appropriate driver.
