Marshal as a JSON list instead of a map. Because set elements are
`comparable` and not `cmp.Ordered`, we cannot easily sort the items
before marshaling.

I didn't clean up the more idiomatic map[T]bool with true values, at
least yet. I just converted the relatively awkward struct{}-valued
maps.

We have two other types of Sets here. Add the basic obvious one too.
Needed for a change elsewhere.

This is an exact copy of the files misc/set/set{,_test}.go from
tailscale/corp@a5415daa9c, plus the
license headers.

This updates all source files to use a new standard header for copyright
and license declaration. Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.
This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

We use this pattern in a number of places (in this repo and elsewhere)
and I was about to add a fourth to this repo which was crossing the line.
Add this type instead so they're all the same.
Also, we have another Set type (SliceSet, which tracks its keys in
order) in another repo we can move to this package later.
