[REQ][RUST] Allow rust generator `useBonBuilder` option for all `library` types

Is your feature request related to a problem? Please describe.

First up, thank you very much for all the work done on the specification and making this incredibly complex topic even possible to begin with

As mentioned in #24312 bon is a nice crate which "provides idiomatic partial application with optional and named parameters for functions and methods".

Since bon can apply to any function, method or struct with version 3.9 it should be possible to make use of bon for all other library types, not just reqwest-trait

Describe the solution you'd like

Extend useBonBuilder configuration option to work for all other library types like reqwest, hyper & hyper0x if applicable or possible

Describe alternatives you've considered

alternatives are the same as mentioned in #24312

Additional context

bon function examples
bon struct examples
bon method examples

Start at the Rust generator's useBonBuilder option and compare how it is handled for reqwest-trait with the other library types mentioned, including reqwest, hyper, and hyper0x. Review the relevant generated Rust library entry points and bon function, method, and struct examples; the work is done when the option consistently applies wherever supported and generated output remains valid.
