fix(cli): Warn on not-run lifecycle scripts with global cache (#25786)

Refactors the lifecycle scripts code to extract out the common
functionality and then uses that to provide a warning in the global
resolver.

While ideally we would still support them with the global cache, for now
a warning is at least better than the status quo (where people are
unaware why their packages aren't working).
