Adriano Sela Aviles 72578de033 ipn/{ipnlocal,localapi},client/local: add per-dst cap resolution for services
Adds two new cap resolution methods alongside the existing PeerCaps:

PeerCapsForService(src netip.Addr, svcName tailcfg.ServiceName) resolves
the service name to its VIP addresses via the node's service IP mappings
and returns caps scoped to that service. Exposed on /v0/whois via the
svc_name query parameter and on client/local.Client as WhoIsForService.

PeerCapsForIP(src, dst netip.Addr) resolves caps against an arbitrary
destination IP. Exposed on /v0/whois via the svc_addr query parameter
and on client/local.Client as WhoIsForIP.

svc_name takes priority over svc_addr when both are present. Invalid
values for either return 400. The existing PeerCaps/WhoIs path is
unchanged: without a service parameter, WhoIs returns only host-level
caps.

Updates tailscale/corp#41632
