net/tsaddr: simplify TailscaleServiceIP
...
netaddr allocated at the time this was written. No longer.
name old time/op new time/op delta
TailscaleServiceAddr-4 5.46ns ± 4% 1.83ns ± 3% -66.52% (p=0.008 n=5+5)
A bunch of the others can probably be simplified too, but this
was the only one with just an IP and not an IPPrefix.

all: adapt to opaque netaddr types
...
This commit is a mishmash of automated edits using gofmt:
gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w .
gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w .
gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w .
gofmt -r 'a.IP.As16 -> a.IP().As16' -w .
gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w .
gofmt -r 'a.IP.As4 -> a.IP().As4' -w .
gofmt -r 'a.IP.String -> a.IP().String' -w .
And regexps:
\w*(.*)\.Port = (.*) -> $1 = $1.WithPort($2)
\w*(.*)\.IP = (.*) -> $1 = $1.WithIP($2)
And lots of manual fixups.
