Matthew Flatt 4a4e12bc8c cs: repair register-finalizer-and-custodian-shutdown 
Refine the approach in 91abd020d1 so that it's only used when needed
to work for the combination of custodian management and unsafe
finalization.

Also, improve the documentation to clarify the constraints on
`register-finalize` due to its implementation in CS by ordered
finalization. This constraint is also reflected in a new `#:ordered?`
argument to `register-custodian-shutdown`. Any existing code that uses
`register-custodian-shutdown` plus `register-finalizer` directly
instead of `register-finalizer-and-custodian-shutdown` would need to
be updated for Racket CS, but code like that should be rare to
nonexistent.

Closes #3352
