Beta Branch add optional external libgd PHP extension support in 123.09beta01

add optional external libgd PHP extension support in 123.09beta01

- PHP usually installs libgd version that is bundled with PHP. However, you can also opt to install a newer version of libgd with PHP. This update optionally allows installing PHP with an external more up to date libgd version for PHP 7.4+ and PHP 8.0-8.1 https://www.php.net/manual/en/image.installation.php
- Add libgd 2.3.3 support libgd/CHANGELOG.md at gd-2.3.3 · libgd/libgd when PHP_LIBGD_EXTERNAL='y' variable is set in persistent config file /etc/centminmod/custom_config.inc prior to running centmin.sh menu option 5 PHP upgrade/recompiles
- External libgd support is handled differently in PHP 7.4+ and PHP 8.0+ compared to PHP 7.0 to 7.3. So external libgd support is only for PHP 7.4+ and PHP 8.0-8.1

with PHP 8.1.0 adds AVIF image support if libheif library is detected. Centmin Mod doesn't install libheif by default. But my test server has experimental libheif library install support which I've been testing.

Hasn't been tested much that's why. Usually for some things in Centmin Mod delays aren't because they haven't been added/enabled but because they haven't been tested as much. Adding something to Centmin Mod is easy, but testing it properly takes quite some time. It's not uncommon for a Centmin Mod feature to undergo weeks/months of active testing when I have the time - most I have ever done for a feature IIRC is 300 test Centmin Mod installation runs in 5 days!
