The control plane hasn't sent it to clients in ages.

I noticed we were allocating these every time when they could just
share the same memory. Rather than document ownership, just lock it
down with a view.
I was considering doing all of the fields but decided to just do this
one first as test to see how infectious it became. Conclusion: not
very.

This moves NewContainsIPFunc from tsaddr to new ipset package.
And wgengine/filter types gets split into wgengine/filter/filtertype,
so netmap (and thus the CLI, etc) doesn't need to bring in ipset,
bart, etc.
Then add a test making sure the CLI deps don't regress.

NewContainsIPFunc returns a contains matcher optimized for its
input. Use that instead of what this did before, always doing a test
over each of a list of netip.Prefixes.

Define PeerCapabilty and PeerCapMap as the new way of sending down
inter-peer capability information.
Previously, this was unstructured and you could only send down strings
which got too limiting for certain usecases. Instead add the ability
to send down raw JSON messages that are opaque to Tailscale but provide
the applications to define them however they wish.
Also update accessors to use the new values.

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.
Updates #6865

Profiling identified this as a fairly hot path for growing a slice.
Given this is only used in control & when a new packet filter is received, this shouldnt be hot in the client.
Add proto to flowtrack.Tuple.
Add types/ipproto leaf package to break a cycle.
Server-side ACL work remains.
