What with PHP 7.4 deprecating the array dereferencing syntax with curly braces, I've been doing some research on where this was supported up to now. Turns out that, as of PHP 7.0, dereferencing array/string literals using curly braces has been supported. See: https://3v4l.org/SlXd2 While the PHP 7.0 changelog makes no note of this, the change was probably part of the PHP 7.0 [Uniform Variable Syntax](https://wiki.php.net/rfc/uniform_variable_syntax) changes. This PR adjusts the `PHPCompatibility.Syntax.NewArrayStringDereferencing` sniff to: * Also recognize curly braces.; * Throw an error for each access detected, i.e. `[1, [20, 21, 22], 3][1][1]` would previously throw just the one error, now it will throw two. Includes unit tests. The actual logic has been split off to a separate `isArrayStringDereferencing()` method to allow it to be re-used for the upcoming sniff which will detect the PHP 7.4 curly brace deprecation.
