Include a TokenRecover contract

[mikeki]

🧐 Motivation

A regular incident in the Ethereum Blockchain is that of accidentally sending tokens to a contract which has no means of recovering them. There are multiple implementations of a TokenRecover contract on github, but I was surpised to see that OpenZeppelin doesn't have one.

📝 Details

I'm attaching a few examples, which could be used for inspiration.

Hi @mikeki! Thanks for the suggestion, it is really appreciated.

There has previously been recover tokens functionality in OpenZeppelin Contracts see: #1474 (comment)
