tree/: Move programmer_delay() out of programmer state machine

Handle the special cases of both serprog and ch341a_spi.
Also rewrite programmer_delay() to handle the two base
cases of zero time and no valid flashctx yet before
handling per master branching.

Additionally, modify the custom delay function pointer
signature to allow closure over the flashctx. This allows
driver specific delay implementations to recover programmer
specific opaque data within their delay implementations.
Therefore programmer specific delay functions can avoid
programmer specific globals.
