Fix Xdebug 3 compatibility with PHP 7.3 and 7.4

[DocLM]

Description

Add version check to Xdebug configuration to match the check used to install Xdebug 3.
Previously only PHP 8 use v3 but now also PHP 7.4 and 7.3 need configuration adjustments to work as expected.
I've also updated Xdebug version to match the latest version (3.1.4) available on PECL at the time of writing.
Since Xdebug 3 use port 9003 as default I've added a configuration variable to allow to specify Xdebug port for php-fpm and workspace container

Fixes #3099 and #3169 if used with default configuration (probably also fixes #3083)

Motivation and Context

Fixes issues caused by the migration to Xdebug 3 for PHP version 7.4 and 7.4.
Also add the ability to select a custom port instead of 9003 for Xdebug in workspace and php-fpm.

A working debugger is one of the most important feature a developer should have.
