Refactor vtoycli compilation script for enhanced clarity and modularity

- Introduce a `compile_vtoycli` function to centralize the compilation logic for different architectures. This function accepts the compiler, library, output binary name, and extra flags as arguments.
- Simplify removal of old binaries by consolidating `rm` commands into a single line.
- Utilize the `compile_vtoycli` function to compile the `vtoycli` tool for x64, ia32, aarch64, and mips64el architectures.
- Improve the check for successful compilation by verifying the existence of all expected binaries before proceeding to strip and move them.
- Streamline the stripping and moving of binaries to their respective directories, enhancing the script's readability and maintainability.
