Change FIRRTL emission to use a simpler syntax for registers without a
reset.  Previously, this used a self-reset with a zero reset signal.
Simplify this to emit a register without a reset.

This does not seem to be required by Scala, but it is required by newer

Change what DataView allows in its type checking to enable Reset to be
viewed as either a UInt<1> or an AsyncReset.  This enables more flexible
DataViews which match already allowable Chisel and FIRRTL connection
semantics.

This utility provides a way to check different versions of type
equivalence in Chisel internals and generates error messages for when
mismatches are found. Specifically, it handles structural vs. nominal
typing as well as strict vs. non-strict width checking.

This adds a new Chisel template for using Chisel with Scala CLI, and
adds some automation for uploading versions of this template on tagged

Remove deprecated "sonatypeRepo" from firrtl compilation unit.  This is
unnecessary given that the firrtl compilation unit uses "commonSettings"
which already include the non-deprecated versions of the Sonatype
Repositories.

This commit reimplements the previous work adding emission of
annotations via the FIRRTL specification v2.0.0 %[[...]] style.
Now all annotations that were previously emitted to the .anno.json file
are emitted in the .fir file. This uses a slightly hacky new internal
mechanism in firrtl that is already marked deprecated to discourage
users from touching it.

This annotation is being handled in mfc via:
  https://github.com/llvm/circt/pull/4665

The convention lets users define how ports with aggregate types are
lowered to verilog.

This PR cleaned up the old build script, split it to common.sc and
builds.sc two files. common.sc is used for declare the dependencies and
project structual for each modules, which can be reused by other
projects for building from source. build.sc is used for build project in
tree.
This commit makes chisel3[2.13.10] able to compile.

Also switch from Mill's BuildInfo to our own

* the firtool version is now included in the BuildInfo
* firtool now must be on the path when publishing, but is not required
  for building or testing
* FirtoolNonZeroExitCode now no longer includes a stack trace

Add new workflow to generate release notes. This workflow can be run
manually via workflow dispatch, but will also run automatically upon
creating a release. The workflow dispatch can be used for testing,
previewing release notes for a potential release, or for generating
release notes for past releases for when the automation has a bug or
didn't exist.

Also update the PR template and CONTRIBUTING guidelines to include
information about the new required labels and automation. Also
streamline the PR template a little bit to nudge developers towards
putting more information in the "Release Notes" section of the PR
template.

This extends the set of circt intrinsics with Chisel wrappers. These have no impact on code not using them.

Remove the _compatAutoWrapPorts method as this does nothing.
