ipn/ipnlocal, net/netns: add node cap to disable netns interface binding on netext Apple clients (#17691)
updates tailscale/corp#31571

It appears that on the latest macOS, iOS and tVOS versions, the work
that netns is doing to bind outgoing connections to the default interface (and all
of the trimmings and workarounds in netmon et al that make that work) are
not needed. The kernel is extension-aware and doing nothing, is the right
thing.  This is, however, not the case for tailscaled (which is not a
special process).

To allow us to test this assertion (and where it might break things), we add a
new node cap that turns this behaviour off only for network-extension equipped clients,
making it possible to turn this off tailnet-wide, without breaking any tailscaled
macos nodes.
