libmaple/flash: Add family-specific FLASH_SAFE_WAIT_STATES.
This is the smallest wait state value that is safe for use when the
MCU is at its fastest rate, not considering overclocking. This
requires moving the FLASH_WAIT_STATE defines above the family include,
so do that, and add the missing #defines (for wait states up to 7).
For the STM32F1, the correct value for FLASH_SAFE_WAIT_STATES is
FLASH_WAIT_STATE_2; say so in the F1-family flash.h.
