[Proposal] Add groupByRaw

[lancepioch]

We already have the following raw methods:

• selectRaw
• whereRaw
• havingRaw
• orderByRaw

I'm willing to submit a PR with support.

@lancepioch do you still intend to do a PR for this case?

[lancepioch]

@rentalhost yeah I'll see if I can throw out a PR for this tomorrow or next week.

@lancepioch I have implemented this feature with two tests (one for the feature itself and another to check if mixed bindings types still works as expected). Do you care if I PR?

You can check here: laravel/framework@d50c82d

If you already got it done, go for it 🥇
