* overload MuxLookup.apply for EnumType
* remove MuxLookup.fromEnum
* add source locators to MuxLookup.apply using macros

These annotations are no longer used now that they cannot affect CIRCT
execution.

* Make read-write inference on by default

Change CIRCT to turn on read-write inference by default.  This is
primarily done because this option was removed in:

running with CIRCT.  This option was removed in:

* Emit FIRRTL spec version in Emitter
* Bump FIRRTL spec version to 1.2.0

Change the assertKnownWidth and assertInferredWidth test utility methods
to check Verilog directly as opposed to doing a full Verilator
compilation.  This dramatically improves the speed of these tests and
should help triage failures if there are problems.

Remove Cat from util

add MuxLookup.fromEnum

Verilator 5.0 emits C++ which requires "-std=c++11".  This is normally
handled by the Verilator configure script.  However, since Chisel
doesn't use this, the lack of this when running with Verilator 5.0 can
result in compilation failures in tests.  Add this flag so that
Verilator 5.0 works.  I have not tested this with earlier Verilator
versions.

* Refactor Shell into BareShell and Shell

Refactor firrtl.options.Shell into BareShell and Shell.  This is done to
enable the leaner BareShell to _not_ provide no command line options
other than "--help".  This enables use cases like the ChiselStage$
object which should not have options that are available to a Shell,
e.g., "--target-directory".

* Use BareShell in ChiselStage$ options (remove -td)

Change the ChiselStage$ object to use BareShell which enables this to
now reject options like "--target-directory"/"-td" which have no
effect.  Add a test that "-td" is rejected by emitCHIRRTL.

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/
