Per IEEE 1800-2017 6.5, variables can be written by one port, including
primitive gate outputs. The code incorrectly disallowed this with the
comment "Gates can never have variable output ports."
Changed elaborate_lnet/elaborate_bi_net calls for gate outputs to pass
true for var_allowed_in_sv, allowing variables as single-driver outputs.

The tgt-sizer target now skips IVL_SCT_PACKAGE scopes (the SystemVerilog
$unit compilation unit scope) instead of erroring. This allows sizer to
work with -g2012 and other SystemVerilog modes.

Modified grammar in parse.y to use identifier_name instead of IDENTIFIER
in function/task declaration rules and hierarchy_identifier rule. This
allows TYPE_IDENTIFIER tokens (which class names become after definition)
to be used as method names.
Changes:
- Function declaration rules (lines 1585, 1605, 1631)
- Task declaration rules (lines 2445, 2472, 2501)
- hierarchy_identifier member access (line 4471)

When $bits() is called with an undefined identifier, the compiler now
properly reports an error instead of silently returning 0.
The fix checks if the argument expression has type IVL_VT_NO_TYPE after
test_width() processing (indicating the identifier couldn't be resolved),
and triggers elaboration to produce a proper error message.

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.
