Jean-François Nguyen 373a4e28b6 pfv.Interface: add support for skipping instructions. 
The `pfv.skip` signal is used to handle cases where the DUT does not
actually execute an instruction (e.g. a no-op), which may prevent some
side-effects (e.g. GPR accesses) from being observable.

Jean-François Nguyen 5ca0001b4b Add data storage check. 
This check is implemented in two parts:
- an implementation-dependant DataStorageModel, which is connected to
  the DUT and emulates bus accesses to a r/w memory.
- a DataStorageTestbench, which checks that a load from a given address
  returns the last value that was stored to it.

Jean-François Nguyen ec7cfdd719 cores/microwatt: move microwatt.py to its own python module. 
Also:
* update dependencies.
* add amaranth-soc as a dependency, in order to reuse its bus
  interfaces (e.g. Wishbone).
* add a `prog` argument to PowerFVSession that overrides the name of
  its CLI.
