This includes changing AsTypeOfSpec to be FunSpec instead of FlatSpec
so that the tests can have more structure.

* Add and use Mill wrapper script (#4119)

This saves developers from having to install a dependency. It also
allows us to drop an old Github Actions dependency that hasn't been
updated in 2 years. This is the standard practice for projects using
Mill on Github.

* Fix boring tap of non-passive source from parent. (#4083)

Expected result is fully aligned, which is what happens
when reading from a probe.

When the source is already at the LCA (from parent)
there's no probe and the secret connections only support
a few commands.

For lack of a way to do, e.g., `:#=` here,
use `read(probe(x))` to get the fully aligned result
that's expected and bored down to the child.

This isn't ideal but fixes this using only the sorts of expressions
and commands that we've already committed to supporting.

Fixes #3557.

This should always return the same type/alignment regardless of where
the original resides, so if the expectation is a fully aligned result
then create one if needed.

* Fix widths for literal values in Bundle literals (#4082)

* Fix widths for literal values in Bundle literals

Previously, the user-specified (or unspecified minimum width) of the
literal would be used in some operations like concatenation.

* Implicitly truncate too-wide literals in Bundle literals

This is to fix a bug in concatenation without breaking things relying on
implicit truncation. This will be a warning in newer versions of Chisel.
