CMake,config.h: Add -DSTIMBUFF_FRAME_PERIOD_MS

This determines the maximum rate at which stimbuffs will be refreshed
with data from their device.
A device may refresh less frequently than this, but not more
frequently. The goal here is to give us control over the max
rate at which a device produces data.
