cores/microwatt: rename CLI tool (microwatt → microwatt_cli).

The CLI tool uses its own __main__.py; as a convention, we will suffix
it with '_cli' in order to avoid name collisions with Python packages
(e.g. an Amaranth core may have its package named after itself).

test: check PowerFV specifications against OPV testcases.
...
- Testcases are translated to JSON by the OPV 'parsetst' script.
- A behavioral model of a single-threaded core is implemented by
coupling PowerFV instruction specs to an execution context (i.e.
registers, memory).
- Testcase traces are reproduced in simulation by the model, and
results are compared to detect compliance bugs.

insn: use records to define instruction encodings.
...
Before this commit, instructions were defined by a sequence of Const
for fixed fields (e.g. PO/XO) and AnyConst for others (e.g. operands).
This approach restricted their use to BMC use-cases, and prevented them
from appearing in VCD traces.
After this commit, an instruction encoding is defined by a Record. As
fields can now be set to arbitrary values, the corresponding InsnSpec
will only assert `pfv.stb` if `pfv.insn` matches a valid encoding (i.e.
fixed fields have correct values). On the other side, BMC testbenches
will drive `pfv.insn` with an AnyConst, and assume `pfv.stb` is high.

This commit integrates it to the 'build' command.

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
