A few JSON regression test entries reference the wrong source or gold
files. There are also two regress-vvp list entries that reference each
other's JSON file.
Use the matching source and gold files for those entries.

The sv_mixed_assign2 JSON entry accidentally references
sv_mixed_assign1.v. Point it at sv_mixed_assign2.v instead.

Check that class objects, dynamic arrays, queues, strings and static
unpacked arrays can not be used as l-value concatenation operands. Check
procedural and continuous assignment concatenations, including single
operand concatenations.

Check that the compiler reports an error for `posedge`, `negedge` and `edge`
event controls on named events. Edge controls can not be used with named
events.
There is already an existing test that checks both `posedge` and `negedge`.
Split it into separate tests so that each invalid event control is checked
independently.

Check that package variables can use explicit static lifetime. Check that
automatic lifetime is rejected for package variables.

invalid target array types are reported as errors.

Check that drive strength can be specified between the net type and the
data type in a net declaration and that vector gate arrays resolve
strengths correctly.

Replace .github/test.sh with a unified set of targets installed
via `make check-*` in ivtest/, thereby removing CI-specific test
coordination. This avoids duplication in the regression logic and
ensures consistent execution between local and CI environments.
PLI1-dependent tests are now correctly controlled via
`configure --enable-libveriuser`.
Currently, the regression suite still depends on an iverilog package,
which must be installed manually at the location specified with
`configure --prefix=*`. Afterward, the complete regression suite
(VVP, VPI, and Python tests) can be run via `make check-installed`
and individual checks can be run with `check-installed-vpi`,
`check-installed-vvp` and `check-installed-vvp-py`.
This version works with the native Windows (mingw64 and clang64)
versions of Perl in MSYS2.
Note that warnings are disabled in the Environment.pm module because
Perl fails to notice that OLDOUT and OLDERR are used when restoring
the STDOUT and STDERR file handles.
When redirection operators are included in a command string passed to
the system() subroutine, it spawns an intermediate shell to handle the
redirection. This is particularly inefficient when running the tests
in MSYS2. Creating our own version of system() based on fork() and
exec() allows us to handle the redirection directly.
