[Improvements]: Remove usage of boost library

[Milerius]

Motivation

Most of the use of boost in the project is replaceable by our own implementations or the standard library.

This passing of dependencies in the project allows us to have more sovereignty, simplify security audits and facilitate compilation in wasm and facilitate the distribution/compilation of the project.

• [x] boost::variant -> std::variant #2565
• [x] boost::any -> std::variant #2539
• [ ] boost::algorithm -> std alternative / ranges
• [x] base64 -> easy to recode (good test task) #2883
• [ ] boost::lexical_cast -> can be recoded or replaced with std::to_string, std::to_chars alternative (good test task for candidate)
• [ ] boost::uuid -> single header file for uuid to recode (good test task for candidate)
• [x] boost::crc -> easy to recode - Under review #2629
• [ ] boost::multiprecision -> https://blog.llvm.org/2020/04/the-new-clang-extint-feature-provides.html (good test task) - https://godbolt.org/z/fanj71nE9

Nice wrap up , can you sort them from easy/small to hard? so we can tackle one by one

While you are at it, maybe also get rid of ruby / rust as the project is in C++?

Also noticed the actual requirements isn't listed here: https://developer.trustwallet.com/wallet-core/developing-the-library/building

As you need Ubuntu 20.04+, ruby > 2.6, latest rust, clang-14. Building wallet-core on Ubuntu 18.04 no longer works.

Rust is something that we would like to extend in the future, most likely moving C++ logic to rust.

Regarding ruby, it's used for codegen our bindings in swift wasm and kotlin, we do not plan to remove it for now, eventually the tool will be re-written in rust
