common/json_tok: allow non-v0 segwit addresses.

Browse source 
Only v0 has specific length restrictions: taproot is v1 32 bytes long,
but explicitly other lengths remain undefined.

I noticed that I added option_shutdown_anysegwit as EXPERIMENTAL in
the last release, but didn't CHANGELOG it.  Then I changed it to
non-experimental as a spec update, but didn't CHANGELOG it then
either, so let's do that now!

    Changelog-Added: Protocol: We now send and accept `option_shutdown_anysegwit` so you can close channels to v1+ segwit addresses.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `withdraw`, `close` (and others) now accept taproot (and other future) segwit addresses.
