e66d4e4c81 tailcfg, types/wgkey: add AppendTo methods on some types
Add MarshalText-like appending variants. Like:
https://pkg.go.dev/inet.af/netaddr#IP.AppendTo

To be used by @josharian's pending deephash optimizations.

05bed64772 types/wgkey: simplify Key.UnmarshalJSON
Instead of calling ParseHex, do the hex.Decode directly.

4037fc25c5 types/wgkey: use value receiver with MarshalJSON
Pointer receivers used with MarshalJSON are code rakes.

I just stepped on one, and it hurt. Turn it over.
While we're here, optimize the code a bit.

7ee891f5fd all: delete wgcfg.Key and wgcfg.PrivateKey
For historical reasons, we ended up with two near-duplicate
copies of curve25519 key types, one in the wireguard-go module
(wgcfg) and one in the tailscale module (types/wgkey).
Then we moved wgcfg to the tailscale module.
We can now remove the wgcfg key type in favor of wgkey.

56a7652dc9 wgkey: new package
This is a replacement for the key-related parts
of the wireguard-go wgcfg package.

This is almost a straight copy/paste from the wgcfg package.
I have slightly changed some of the exported functions and types
to avoid stutter, added and tweaked some comments,
and removed some now-unused code.

To avoid having wireguard-go depend on this new package,
wgcfg will keep its key types.

We translate into and out of those types at the last minute.
These few remaining uses will be eliminated alongside
the rest of the wgcfg package.
