Wanda 8bf4f77616 sim: use Format.* for VCD output, remove hdl._repr. 
This also changes `decoder` a bit: when an enum is used as a decoder,
it is converted to a `Format.Enum` instead. The original enum is still
stored on the `decoder` attribute, so that it can be propagated
on `Signal.like`.

Catherine 7dd93bea57 Document RFC 62. 
This includes a few minor code changes:
- Removing redundant `lib.memory.Memory.Init = hdl.MemoryData.Init`
  re-export;
- Renaming `FrozenError` to `FrozenMemory` and moving it to `.hdl`;
- Marking `ReadPort` and `WritePort` as `@final`.

Catherine 3c6f46717b lib.wiring: allow reset-less signals in interfaces. 
This check was originally added out of abundance of caution, but since
then it was observed that reset-less-ness is purely an implementation
detail (see #1220), and furthermore it interferes with adaptation of
`FIFOInterface`` signals (where `[rw]_data` are reset-less) for RFC 61.

Wanda 09d5540430 hdl._mem: add MemoryData class. 
This implements half of RFC 62. The `MemoryData._Row` class will be
implemented later, as a follow-up.

Catherine f261071f7c docs/guide: clarify section on IOBufferInstance. 
There is no reason to assign names to `IOBufferInstance` submodules
because it's ignored anyways.

Catherine 6ce82848d9 lib.memory: Memory.{r,w}_ports→.{read,write}_ports. 
The abbreviated form was initially added to match `lib.fifo`, but it
looks very out of place on `lib.memory`, and we may be moving away from
such heavy use of abbreviations anyway.

While technically a breaking change, these attributes have very narrow
usefulness and so this change qualifies as "minor".

Catherine b9c9948038 docs: use :py: role for inline Python code, not :pc:. 
I originally picked :pc: as it is short for "python code", but it is
obscure and :py: is not taken, so a much more obvious role can be used
instead. Also, we all typo :pc: as :py: all the time anyway.
