Extend the probe modifier case class, `ProbeInfo`, to include information
about the optional layer color of this layer.  Extend emission to properly
write this out to FIRRTL text.

Add a memoized (via a `lazy val`) member to Layer that returns the FIRRTL
"full name" of that layer.  This includes all the parent layers prefixed
with interleaves periods.

This is memoized to avoid unnecessarily recomputing the partial prefixes
of parents.

This ensures that the specific build tools show up in the Table of
Contents.

* Remove binary compatibility checking on 6.0.0
* Update .mergify.yml with 6.x (drop 3.5.x)
* Update PR Template (add 6.x, drop 3.5.x)

* [binder] Emit invalidate according to the value flow
* [binder] Use inferred result type in primitive ops to avoid handling zero-width operands

* Use "dep" instead of deprecated "lib"
* Add _root_ to `import circt.stage.ChiselStage`
  * Also add comment describing how this disambiguates from
    chisel3.util.circt when the user does `import chisel3.util._`
* Bump versions in Github workflows

Refactor panama binding and converter framwork

In the future, we should rename them to org.chipsalliance...
But for now, since we need to access internal API of chisel, panama is
using the prefix of chisel3

- split binder into two projects: Java Module circtpanamabinding and
  ScalaModule panamaconverter, in the future, OMEvaultor will be split
  from converter and get rid of dependency from chisel.
- remove original test, add a small lit+FileCheck test in
  lit/tests/PanamaConveter to show how to write test.

a Pure LLVM Lit test framework

Users are now able to check whether a Data is visible from the
current context via `chisel.reflect.DataMirror.isVisible`.

* Bump versions
* It now tabs every line included in the Release Notes section of
  the PR template

Also fix website API doc link generation, links prior to 3.5.4 are not
valid (that is when we started publishing the unidoc properly so that it
gets picked up by javadoc.io and the like).

Using `Output()` shouldn't drop important type information,
only override the specified direction to force alignment.

Until #3647 is addressed, use `cloneTypeFull` to get the expected behavior.
The cloned direction information is unnecessary but is
overridden by the coerced direction.

cc #3647.

The automation around automatically determining released versions of
Chisel and generating content for the website would fail in the period
between tagging a new release and the corresponding artifacts actually
being released to Maven Central. This would even prevent the CI job
trying to push the release to Maven Central.

Now, the logic for determining releases will filter for those actually
pushed to Maven Central.

* Make already deprecated APIs package private
* Add deprecation warnings to a few that we missed

* Bump SBT to latest (1.9.8)

* [CI] Change all ubuntu runners to ubuntu-22.04

This bumps some things running on the older runner which seems to have a
problem with SBT 1.9.8. It also removes any uses of ubuntu-latest to
ensure that we control the version explicitly.

* Width, KnownWidth, and Unknown width promoted to package chisel3
* Other classes moved to new package private chisel3.internal.firrtl.ir

Also change to an object (from a def) so that it shows up in ScalaDoc
search.

This avoids starting any Bloop servers which avoids hangs in CI.

* Revert "[binder] Remove firtool-1.61.0 features"
* [binder] Implement OM
* [binder] Implement probe IR emissions
* Change Trace API to only trace leaves (#3682)

Change the behavior of the Trace API to only trace leaves.  This aligns
with recent changes to CIRCT which error if annotations are applied to
aggregates which are then mandatorily split due to FIRRTL ABIs.  This
should have no practical effect on use of the Trace API only that
downstream consumers will need to work at the level of leaf types and not
on aggregates.

* [binder] Truncate for aggregate connection
* [binder] Set `inner_sym` only when needed
* [binder] Set module visibility
* [binder] Add function for exporting split verilog
* [binder] Support secret ports
* [binder] Refer with `SourceInfo` instead of `MlirLocation`
* [binder] Emit IR for probe read
* [binder] Handle secret ports for instance
* [binder] Fix extmodule emission
* [binder] Handle secret commands
* [binder] Handle probe ops without `Node`
* [binder] Flush the buffer at the end of `Writable` streams
* [binder] Keep original integer types from foreign API
* [binder] fix return type of asAsyncReset
* [cd] Bump CIRCT from firtool-1.61.0 to firtool-1.62.0

To override which firtool is used by Chisel, users should now set
environment variable CHISEL_FIRTOOL_PATH (rather than the old
FIRTOOL_PATH).
