GNU Readline should be replaced with libedit

Description

The following when using Autotools build system:

./buildconf
./configure --with-readline
# or ./configure --with-readline --enable-phpdbg-readline
make

Results in successful build, but the linked library GNU Readline is licensed under the GNU GPL 3 license, which means that PHP then shouldn't be distributed to anyone. PHP provides linking with the libedit library (--with-libedit) as a replacement in this case. However, build system should not contain such issues. This is not that obvious for people just starting to build PHP and trying to provide it to other users.

There is https://github.com/php/php-src/pull/13184 where the GNU Readline is replaced with libedit only.

Should we target PHP 8.4?
