BREAKING(unstable): Use hosts for net allowlists (#8845)

Allowlist checking already uses hosts but for some reason 
requests, revokes and the runtime permissions API use URLs.

- BREAKING(lib.deno.unstable.d.ts): Change 
NetPermissionDescriptor::url to NetPermissionDescriptor::host

- fix(runtime/permissions): Don't add whole URLs to the 
allowlist on request

- fix(runtime/permissions): Harden strength semantics:
({ name: "net", host: "127.0.0.1" } is stronger than 
{ name: "net", host: "127.0.0.1:8000" }) for blocklisting

- refactor(runtime/permissions): Use tuples for hosts, make 
the host optional in Permissions::{query_net, request_net, revoke_net}()
