[Enhancement] Improve Magento.Annotation rules

[lenaorobei]

Description

PHP CodeSniffer goes out-of-box with beautifier tool (phpcbf). To use this functionality sniff should throw fixable warning/error and provide fix (tokens replacement, content change, etc).
Now rules under Magento/Annotation raise regular warnings so annotation issues cannot be fixes automatically by phpcbf.

Expected behavior

The sniff throws fixable warning instead of warning and provides fix for an issue it detects.

Benefits

Annotation issues will be fixable automatically by phpcbf tool.
