Catherine 6f44438e58 hdl._ir,hdl._nir,back.rtlil: new intermediate representation. 
The new intermediate representation will enable global analyses
on Amaranth code without lowering it to another representation
such as RTLIL.

This commit also changes the RTLIL builder to use the new IR.

Catherine ea3d6c9557 docs/reference: document compat guarantee, importing, shapes. 
This commit also contains a related semantic change: it adds `Shape`
and `ShapeCastable` to the `__all__` list in `amaranth.hdl`. This is
consistent with the policy that is laid out in the new documentation,
which permits such additions without notice.

Reexports of `amaranth.utils` functions are removed from
`amaranth._utils` to avoid a circular import issue (for `deprecated`).
Since this is a private module, this should not be a problem.
