This does not seem to be required by Scala, but it is required by newer
versions of SemanticDB (and thus to use Scala Metals).

- Enable .viewAsSupertype to work on Records
- fix a nondeterminism error in DataView noticeable on error reporting

Enable a user to define Scala-time properties on an Interface.  These
properties require a conformance to examine.  This enables patterns where
a client wants to configure itself based on knowledge of the component,
e.g., when the client is a testbench.

Make the frequency a legal value (14 days).

Fix a bug in naming where a Module that took a Unit parameter could cause
naming to crash.  This is, admittedly, a very weird pattern, but can occur
if you have a type-parametric module where certain type parameterizations
can be Unit.

Fix #3245.

Fix a bug in the new BoringUtils.bore API where this would generate
invalid FIRRTL if the user did boring which created a path that went up to
an LCA and then down.  Change the internal leastCommonAncestor utility to
also return the LCA module as this avoids a second call to compute the
LCA.

Fixes #3239.
