[TASK] Add thecodingmachine/safe (#1453) (#1366)

Safe-PHP https://github.com/thecodingmachine/safe provides
rewrites of PHP functions to throw an exception instead of
returning `false` when an error is encountered.

This will allow us to drop out custom `preg_*` wrapper class
and to increase type safety in our codebase.

Also drop the PHP-CS-Fixer rule that adds a trailing backslash
to calls to native PHP functions (as this would change the
Safe-PHP calls back to their unsafe versions).

The actual code changes will come in subsequent commits.

Part of #1168
