Enable lexical binding in all .el files

Hi-Angel · Hi-Angel · commit 3e1058cb3b60 · 2024-09-30T10:17:24.000+03:00
Upstream Emacs has made lack of the directive a warning. So enable it
explicitly everywhere. It provides various benefits such as better
introspection by the compiler into the code and optimizations.

Fixes a bunch of warnings:

      Error: file has no ‘lexical-binding’ directive on its first line
