Replaced old markdown Issue template with new GitHub forms templates (#3468) 
This PR replaces the old markdown issue template with the new YAML based form templates for GitHub, this allows us to enforce required fields and also auto-tag with labels.

This doesn't remove the ability to open a blank issue, but it is obscured so it is not the primary thing people are likely to do.

This also added link entries in the issue creation page to link to the Discussions tab, Community Slack, and IRC channel.

Tristan Gingold 4543751a77 synth_sf2: add -discard-ffinit option to discard ff initial value 
sf2 ff have no initial values, but some IP cores use initial values.
In order to use those cores on sf2, it is required to discard the
initial value (to be carefully used).

Ethan Mahintorabi 114253cd54 Improves ABC command runtime by 10-100x 
After speaking with the author of ABC he let me know that ifraig is a very old command, and that &get; &fraig -x; &put is over 100x faster than ifraig with improved PPA results.

After making the change I confirmed that this is in fact a major speed up. On our internal designs in O(millions) of standard cells we saw multi hour reductions in runtime.

Also included is an improvement to the dress command. Using AIG based transformations removes the spec it SATs against. Proving the input blif will make sure that no matter what commands are run the dress command can still do its job. I noticed a regression against some LUT mapping jobs that prompted me to fix this.

KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

Jannis Harder 4ad13c647e clk2fflogic: Generate less unused logic when using verific 
Verific generates a lot of FFs with an unused async load and we cannot
always optimize that away before running clk2fflogic, so check for that
special case here.

Jannis Harder efd5b86eb9 aiger: Add yosys-witness support 
Adds a new json based aiger map file and yosys-witness converters to us
this to convert between native and AIGER witness files.

Jannis Harder 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.
