rCOMM478edf15de16: [services] Tunnelbroker - Creating `build.rs` file for building and linking C++…

Summary

This diff is a part of the flat diffs stack to transform the current Tunnelbroker project into a Rust app by calling the current C++ codebase from Rust. The related transition task is ENG-1072.

This diff creates a Cargo build.rs file which builds and links the current C++ codebase to the Rust application.

Related Linear task and discussion: ENG-2093

CI Notice:
The CI will fail on this and further diffs until the D5461 where the changes to CI build commands are made.
This stack will be landed all in one to prevent CI from failing on diffs out of this stack.

Test Plan

1. CI Testing:
These diff changes are included as a part of the stack in the later D5461 diff, where the changes to CI build commands are made. The CI succeded on the D5461 which reflects that this changes are passing the build.

2. Manually testing:
These diff changes can be tested in the middle of the stack at D5436. To test it patch to D5436 using arc patch D5436, run nix develop. Go to tunnelbroker service directory services/tunnelbroker and run the Cargo building process cargo build or cargo run.
The Rust application will be successfully built.

services/tunnelbroker/build.rs
16 ↗	(On Diff #17735)	We are using this function instead of passing the string path directly because the `CFG.exported_header_dirs` wants an absolute path and we are making it here from the relative.
30 ↗	(On Diff #17735)	We are using the `get_cpp_sources` function to traverse the directory and get all the `.cpp` inside to be built.

Adding of -w flag to the C++ building process to suppress flooding of warnings.

8–10 ↗	(On Diff #17865)	feel like this is a bit hard to read, and we should avoid explicit unwraps
11 ↗	(On Diff #17865)	`String::from` and `.to_string()` should be redundant
