Feature: Add Support for PHP HEREDOC Strings

PHP has support for HEREDOC strings. This allows large string blocks to be set between delimiters and vim supports syntax highlighting within these blocks.

In PHP in vim, using a HEREDO specifier such as SQL will cause vim to highlight the given block:

<?php
$my_query = <<<SQL
SELECT * FROM my_tables WHERE foo='bar';
SQL;

This proposal is to have the same kind of support for GraphQL queries:

<?php
$my_query = <<<GQL
{
    posts {
        id
        title
        author
    }
    category
}
GQL;
