2a68eee5f1 xprop: Test fixes and abort on test failure 
Use `$finish(0)` to silently exit even when using recent iverlog
versions. Run `write_verilog -noexpr` before `write_verilog` as the
latter can modify the design.

This also enables checking the tests results, as xprop should be in a
state where the existing tests pass.

26a6c60478 Add test for typenames using constants shadowed later on 
This possible edge case came up while reviewing #3555. It is currently
handled correctly, but there is no clear test coverage.

6d021f04d4 tests: Fix path of yosys invocation in xprop tests 
For now xprop test failures are still expected and ignored, but without
this change, they did not even run unless the yosys build was in path.

777c589e85 Handle range offsets in packed arrays within packed structs 
This brings the metadata for packed arrays in packed structs
in line with the metadata for unpacked arrays, and correctly
handles the case when both lsb and msb in an address range are
non-zero.

71e7e09092 verilog: Support module-scoped task/function calls 
This is primarily intended to enable the standard-permitted use of
module-scoped identifiers to refer to tasks and non-constant functions.
As a side-effect, this also adds support for the non-standard use of
module-scoped identifiers referring to constant functions, a feature
that is supported in some other tools, including Iverilog.

4d334fd3e3 smt2/smtbmc: Fix FF witness data for fine grained or multi chunk FFs 
The witness metadata was missing fine grained FFs completely and for
coarse grained FFs where the output connection has multiple chunks it
lacked the offset of the chunk within the SMT expression. This fixes
both, the later by adding an "smtoffset" field to the metadata.

f041e36c6e smtbmc: Add native json based witness format + smt2 backend support 
This adds a native json based witness trace format. By having a common
format that includes everything we support, and providing a conversion
utility (yosys-witness) we no longer need to implement every format for
every tool that deals with witness traces, avoiding a quadratic
opportunity to introduce subtle bugs.

Included:

  * smt2: New yosys-smt2-witness info lines containing full hierarchical
    paths without lossy escaping.
  * yosys-smtbmc --dump-yw trace.yw: Dump results in the new format.
  * yosys-smtbmc --yw trace.yw: Read new format as constraints.
  * yosys-witness: New tool to convert witness formats.
    Currently this can only display traces in a human-readable-only
    format and do a passthrough read/write of the new format.
  * ywio.py: Small python lib for reading and writing the new format.
    Used by yosys-smtbmc and yosys-witness to avoid duplication.
