Pushes to main will now have SNAPSHOTs based on `git describe --tag`.
Also run CI workflow (which includes publishing) on push to any tag and
enable workflow_dispatch.

Create deprecated alias in package chisel3.util.

Move LFSRSpec, QueueSpec, and QueueFlushSpec to integrationTests for
some CI parallelism.

Update Mergify config and add generation script to this repository

Also slight quality-of-life improvement to comments in the template.

Updated for new main branch and 3.6.x.
Generated with .github/mergify/gen-config.sc

Derived from original Ammonite script:
https://github.com/ucb-bar/chisel-repo-tools/blob/d3432790d746a3e3643acc843377f0d82b830466/scripts/mergify.sc

* Change artifact to org.chipsalliance::chisel:5.0-SNAPSHOT
* Fix website to point to renamed repo (chisel)
* Add "unipublish" for single artifact publishing

It is a new pseduo-project in the SBT build that aggregates build
artifacts from the real projects into a single artifact. It must now be
used for publishing and MiMa binary compatibility checking.

There are also other changes needed for publishing under
org.chipsalliance, namely we have to publish to a different sonatype
snapshots repository: https://s01.oss.sonatype.org/

Remove the FIRRTL backend.  This does not remove FIRRTL serialization,
just the SFC Transforms that create EmittedFirrtlModule annotations.  A
FIRRTL circuit can still be serialized to text in the normal way.

Remove everything from WIR.scala (Working IR) which is not actually IR.
I.e., this removes everything except CHIRRTL constructs and Kind/Flow.
A method is moved into CheckTypes that is used by Chisel to determine
connection validity.  This was unnecessarily bouncing through
WrappedType when it can be simplified to not do the boxing.
