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.

aaec7e0d27 tracer: return default name on unrecognized opcode. 
The default name is more commonly returned on code such as:

    x, y = Signal(), Signal()

The case where the opcode is not recognized is only encountered
when older Amaranth is ran on a newer Python interpreter (with more
opcodes).

Returning None instead of a name here caused issues in the RTLIL
backend, which would incorrectly use $\d+ names for ports, since
the RTLIL backend assumed the name of a signal is always a string.

Fixes #733.

2ca421dea8 back.rtlil: add assertions guarding against $\d+ port names.
