Add a new utility, SparseVec.  This exposes a normal Vec-like dynamic
access API.  However, the dynamic access is implemented one of three ways:

  1. Using a binary decoder
  2. Using a one-hot decoder
  3. Using when statements

This is added to better support a design pattern ("vec--decoder pattern")
where a large, sparse vector is used to describe a decoder.  This pattern,
if unchecked and used in a parametric generator, can cause the vector to
grow extremely large and cause backend tools to complain.

Specifically, Cadence tooling is known to set limits on the addressable
range of a "memory" and will error if these are exceeded.  This
vec--decoder pattern can easily exceed this if designers are not careful.

This fixes Scala compiler warnings in Scala 2.13.12 requiring type
ascriptions on public implicit definitions.

No non-internal existing functionality intended to be changed.

"Alignment" interface (internal) does change.

DataMirror methods implemented in terms of Alignment no longer require the Data
to be hardware, allowing walking (bare) Chisel types and their alignments.

Class definition components cannot have any annotations.

* Added disallowIOCreation as a public API

* Added scope where IO is illegal

Switch from install-circt v1.0.0 to v1.1.1.  There is no major change to
functionality other than this switches to using a shell script instead of
scripting in a GitHub composite action.  This also fixes a bug related to the
action not working in a container environment.  (This is not a problem for
Chisel.)
