Remove toString of dangerouslySetInnerHTML (#17773)

As far as I can tell, the toString call was added here:

https://github.com/facebook/react/commit/00297a5712eb6e9f64d0b4d677b10d9d344fef21#diff-5574f655d491348f422bca600ff6711dR887

It was never really needed. Subsequently when we added Trusted Types,
this needed to be changed to a special call but we really should just
always let it pass through.
