elisp-mode.el: Disable Flymake byte-compile backend in untrusted files

To address serious security issues (CVE-2024-53920), disable
`elisp-flymake-byte-compile` except in those files explicitly

completion if the current file is not trusted.

(trusted-content-p): New function.

* lisp/progmodes/elisp-mode.el (elisp--safe-macroexpand-all):

(elisp--local-variables): Use it.
(elisp-flymake-byte-compile): Disable according to `trusted-content-p`.

Initial child frames based on master

This is based on a diff from 2024-10-15 which still applied.
Since then, I've inadvertantly modified the igc branch so that
it is no longer possible to get a clean diff of what has changed
since I created the branch.

(cherry picked from commit 83245d2269be357db2fff8baa17adb4b05f97aed)

Fix for xt-mouse-tests.el broken in prior commit

xt-mouse-tests not turning on xterm-mouse-mode if it was already
on did not work with xterm-mouse-mode being set to t by default.
It turns out that xt-mouse-tests already does not report proper
results when called inside a running Emacs session so the code
path is not useful anyways.

* test/lisp/xt-mouse-tests.el (with-xterm-mouse-mode): Always
turn on xterm-mouse-mode, even if it is already on.
