feat(operate): Adds a .operate() and alias .o() operator

Allows you to apply operator functions without them needing to be on the
`Observable.prototype`. Most useful for library authors where adding
RxJS operators to the prototype can cause issues for their users.

This solves a similar problem to `stream::operator()` function bind
syntax but doesn't require language support, so works in TypeScript.
