Add compile-angel

[jamescherti]

Add the compile-angel package.

The compile-angel package automatically byte-compiles and native-compiles Emacs Lisp libraries. It offers:

• (compile-angel-on-load-mode): A global mode that compiles .el files before they are loaded.
• (compile-angel-on-save-local-mode): A local mode that compiles .el files whenever the user saves them.

The compile-angel modes speed up Emacs by ensuring all libraries are byte-compiled and native-compiled. Byte-compilation reduces the overhead of loading Emacs Lisp code at runtime, while native compilation optimizes performance by generating machine code specific to your system.
