* Refactor V3Delay for extensibility
Introduce the concept of an "NBA Scheme", which is the lowering pattern
we can use for various variables that are the targets of NBAs.
E.g.:
- ShadowVariable (old default scheme)
- FlagShared (old array set flag scheme)
- ValueQueueWhole (recent dynamic commit queue)
We now analyse all AstAssignDly before making any decisions on which
scheme to apply. We then choose a specific scheme for each variable that
is the target of an NBA, and then all NBAs targeting that variable use
the same scheme. This enables easy mix and match of schemes as needed,
while remaining consistent by design after extensions.
Output is perturbed due to node insertion order, but no functional
or performance change is intended.
The necessary options to support C++ coroutines vary greatly between
compilers, its versions, and the standard library being used. This
patch makes the check for coroutine support more robust by adding a
declaration of a coroutine variable, instead of just including the
header. It also makes sure that the HAVE_COROUTINE and
CFG_CXXFLAGS_COROUTINES flags are always set together, and only when
coroutine support is detected.
Documentation states that minimum of all reported coverage of all signals in a line should be taken.
Previous logic would break if there were any signals with zero coverage followed by signals with
nonzero coverage - a minimum from those nonzero toggle count would be taken, disregarding zero
coverage of previous signals.

`$psprintf` is a non-standard system function present in some other
simulators, and has been rejected for standardization by IEEE because
of being basically the same as `$sformatf`.
To encourage users to fix their codebase, a warning is emitted by
default, but it gets otherwise interpreted as `$sformatf` as early as
during lexing.
