bug#63871: 29.0.91; JIT native comp triggered to compile loaddefs repeatedly on require

[Jimmy Wong]

The problem is not that it does something when it compiles, the problem is it should not have triggered a compilation at all and pops up a buffer. This messes up the buffer order when restoring a session with desktop mode on restart.

Reproduction:

1. emacs -q -nsl --eval="(require 'cl-lib)"
2. C-x b TAB
3. Select *Async-native-compile-log*
4. The following is printed

```emacs-lisp
Compiling /opt/local/share/emacs/29.0.91/lisp/emacs-lisp/cl-loaddefs.el.gz...
uncompressing cl-loaddefs.el.gz...
uncompressing cl-loaddefs.el.gz...done
Compilation finished.
```

Expectation:

This behavior is observed when any packages in ~/.emacs.d/elpa/
autoloads and require cl-lib, org or tramp as well.

The simple act of requiring a built-in Emacs package should not trigger
a JIT native compilation on an Emacs installation built with
`--with-native-compilation=aot`.

And it doesn't. cl-loaddefs has the "no-native-compile: t" thingy in
the file-local variables, so the native-compilation does nothing.

So I don't see any bug here, and I'm closing this bug.
