Add a development-only bootloader command that requests a chip erase after the USB response has been sent. Expose the command through the Python bootloader client and defer execution until outgoing transport writes are idle.

No, the user row is not reset by chip erase.

Why all the effort to wait until the response is done and not do it right away when handling OP_CHIP_ERASE? We do it too for the hww reset and reboot API calls in the firmware - the client simply knows to not expect a response in these cases.

Right, we are pretty unique in having a request/reponse protocol and allow some requests to not have responses, so I totally forgot about it.

It was useful to restore debug access during experiments with bootloader.
