What changed in this PR

Addresses #3519 by distinguishing F# functions from delegates in Fable’s shared overload-name generation, preventing name collisions between those overloads.

Changes:

• Adds a delegate-specific prefix to type names used to calculate overload suffixes.
• Updates comparer factory signatures in the TypeScript and Rust runtime sources to match delegate-based callers.
• Adds regression tests for function, Func, and Action overloads across five targets.
