abc: Exposes dont_use flag in ABC 
ABC's read_lib command has a dont_use
cell list that is configurable by the user.

This PR exposes that option to Yosys.

See
5405d4787a/src/map/scl/scl.c (L285)
for documentation on this option.

Martin Povišer 6d9cd16fad cellaigs: Drop initializer list in call to `IdString::in` 
Remove superfluous curly braces in call to IdString::in to address
a compilation error (reproduced below) under GCC 9 and earlier.

Charlotte ce245b5105 cxxrtl_backend: respect sync `$print` priority 
We add a new flow graph node type, PRINT_SYNC, as they don't get handled
with regular CELL_EVALs.  We could probably move this grouping out of
the dump method.

Charlotte 7f7c61c9f0 fmt: remove lzero by lowering during Verilog parse 
See https://github.com/YosysHQ/yosys/pull/3721#issuecomment-1502037466
-- this reduces logic within the cell, and makes the rules that apply
much more clear.

Charlotte 4e94f62116 simlib: blackbox `$print` cell 
It's possible to `generate` the appropriate always blocks per the

Charlotte a1de898fcc fmt: merge fuzzers since we don't rely on BigInteger logic 
This is per fmt's (effective) use, as it turns out, so we're not losing
any fidelity in the comparison.

Charlotte 3571bf2c2d fmt: fuzz, remove some unnecessary busywork 
Removing some signed checks and logic where we've already guaranteed the
values to be positive.  Indeed, in these cases, if a negative value got
through (per my realisation in the signed fuzz harness), it would cause
an infinite loop due to flooring division.

Charlotte 2ae551c0af fmt: fuzz, fix (remove extraneous + incorrect fill) 
"blk + chunks" is often an overrun, plus the fill is unnecessary; we
throw blk away immediately.

Charlotte d9e4582558 fmt: handle part with unspecified padding in `emit_rtlil` 
e.g. `$displayh(8'ha)` won't have a padding set, because it just gets
`lzero` set instead by `compute_required_decimal_places`.

It also doesn't have a width.  In this case, we can just fill in a dummy
(unused) padding.  Either space or zero would work, but space is a bit
more distinct given the width field follows.

Also omit writing the width if it's zero.  This makes the emitted ilang
a little cleaner in places; `{8:> h0u}` is the output for this example,
now.  The other possible extreme would be `{8:>00h0u}`.

Charlotte 28bd3a4b5d fmt: don't overrun fmt string buffer 
For input like "{", "{1", etc., we would exit the loop due to
`i < fmt.size()` no longer being the case, and then check if
`++i == fmt.size()`.  That would increment i to `fmt.size() + 1`,
and so execution continues.

The intention is to move i beyond the ':', so we do it only in that
case instead.

Charlotte 51d9b73107 fmt: tests completing again 
We need to invoke "read_verilog" manually, since the default action on
input files is to defer processing.  Under such conditions, we never
simplify the AST, and initial $prints never execute.
