[turbofan] Introduce CallDescriptorOf helper for safety.

[turbofan] Introduce CallDescriptorOf helper for safety.

This introduces a dedicated getter to extract call descriptors from
operators of call nodes (i.e. call and tail-call) to ensure that all
accesses are const-correct. An implicit cast of constness is undefined
behavior and hard to spot without sanitization.
