Remove yaf/mcrypt from all-modules fixtures; fix wildcard version resolution

yaf and mcrypt are not available for PHP 8.3.x (dropped upstream).
The default PHP version was changed to 8.3.x in the previous commit,
so tests using PHP 8.3.30 no longer have these extensions.

- Remove ext-yaf from php_all_modules_composer/composer.json
  (composer install was failing: ext-yaf not found in system)
- Remove yaf and mcrypt from php_all_modules/.bp-config/options.json
- Fix ItLoadsAllTheModules to resolve wildcard default version (e.g. '8.3.x')
  to the highest matching exact version in the manifest, instead of doing
  an exact string match that would always fail to find any modules
