feat(builtins): add resolve_alias_opt [NET-528]

[justprosh]

Description

Provide a non-throwing method to resolve alias.

Motivation

We often call Srv.resolve_alias to check whether or not a service exists, but this method throws an error in the absence of this alias, which pollutes nox logs:

Proposed Changes

Implement Srv.resolve_alias_opt:

service Srv:
  resolve_alias_opt(alias: string) -> ?string
