as enum member values.

See #755.

5f094a23eb hdl.ast: Test *Castable subclasses on definition. 
The __init_subclass__ method fires on class definition rather than use.
It also has the bonus impact that no __new__ method is defined, so the
classes can be correctly detected as mix-in classes by modules such as
enum.

a0307c343d docs: disambiguate Cat(a, b, ...) support for more than 2 arguments 
I had this confusion while reading the doc.

Someone else also likely did:

80343d1c4c hdl.ast: warn on fencepost error in Signal(range(x), reset=x). 
Also, relax the language reference inset from "warning" to "note"
since this is no longer something developers have to keep in mind
explicitly.

32eabd9372 hdl.ast: remove Value.__hash__. 
This is already undefined when defining `Value.__eq__`, and it makes
typecheckers (mypy, pyright/pylance) unhappy.

e2ce959c90 build.run: Handle UTF-8 encoding errors in SSH output gracefully 
In some cases, a toolchain might produce shell output that isn't correct
UTF-8. To avoid crashing in such cases, pass errors="replace" to
bytes.decode.

For example, Lattice Diamond uses the Latin-1 encoding for some reason.
This recently broke my setup because the month turned to "März" in a
German locale:

0c4fda92fe hdl.ast: accept any constant-castable expression in Signal(reset=). 
See amaranth-lang/rfcs#4.

This functionality was not explicitly specified in the RFC but it
falls under "anywhere an integer or an enumeration is accepted".

14e73a73de hdl.ast: do not cast comparand to shape in Shape.__eq__. 
This doesn't match how other Python comparison operators work.
E.g. `1 == int("1")` but `1 != "1"`.

35561ea11a lib.data: improve reset value handling for Union. 
* Reject union initialization with more than one reset value.
* Replace the reset value specified in the class definition with
  the one provided during initalization instead of merging.

c7ef05c894 lib.data: improve annotation handling for Struct and Union. 
* Annotations like `s: unsigned(4) = 1` are recognized and
  the assigned value is used as the reset value for the implicitly
  created `Signal`.
* Base classes inheriting from `Struct` and `Union` without
  specifying a layout are recognized.
* Classes that both inherit from a base class with a layout and
  specify a layout are rejected.

fcc4f54367 lib.data: make Field() immutable. 
Mutability of Field isn't specified by the RFC and can cause issues
if the objects stored in Layout subclasses are mutated. There isn't
any reason to do that (the subclasses themselves are mutable and
handle that correctly), so disallow it.

732d62eb24 Move most of setup.py to pyproject.toml. 
The custom setuptools_scm configuration is removed. It was buggy (for
the case of a dirty worktree exactly at the tag, it did not append
`+dirty`) and otherwise is only different from node-and-timestamp by
appending `.dirty` instead of `.dYYYYMMDDHHMMSS`. The latter is
preferable anyway.
