Add SARIF output format

[llaville]

Feature request

Summary

With commit 7c0334c, I've recently allow to add new output format easily with the Reporter extension. Now it's turn to add SARIF in output formats list.

Description

SARIF (Static Analysis Results Interchange Format) is an OASIS Standard that defines an output file format. The SARIF standard is used to streamline how static analysis tools share their results by implementing a subset of the SARIF 2.1.0 JSON schema.

Other Static Tool Analysers like

• PHPMD add an implementation since v2.10.0
• Exakat add its own implementation since v2.1.8
• PHPStan has not yet an implementation, but a PR was proposed

Because I don't found any PHP library that support SARIF v2 specifications, I've published a PHP SDK as a new bartlett/sarif-php-sdk package already available on packagist that implement the full v2.1.0 specifications.
