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.

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.
