sp-core: Rename VrfOutput to VrfPreOutput (#2534)

Browse Source 
This will make more sense after
https://github.com/paritytech/polkadot-sdk/pull/2524 since the
schnorrkel type for VRF outputs is also renamed in the latest version.
Can be reviewed independently though.

Can be merged after https://github.com/paritytech/polkadot-sdk/pull/1577
so that there is less pain for @davxy.
