target/testee: manage target->state

The testee target is usefull for certain non-cpu pass-through
situations, for example in the case of a spi flash mapped to the DR of
a JTAG tap, as is the case for most FPGAs with SPI flashs behind them.

We just manage the RUNNING/RESET/HALTED state in the testee driver to
support it being halted which is a requirement for flash banks.
