Updated PHP-DI support and added to benchmark 4 and 5

PHP-DI V3.0 has evolved a lot, so I updated the code. I was also able to add it to benchmark 4 and 5 since it no longer requires annotations (they are now optional).

The numbers are worse for PHP-DI now :p but I was expecting that since now the "configuration" part is more complex and powerful. If I find some time I'll add more benchmarks with some caching enabled (for containers that support it).
