primitives: Fix alloc feature 

We have an `alloc` feature but we are unconditionally using
`extern crate alloc`, this is broken - clearly we need to add a `no-std`
build for `primitives` in CI.

Feature gate the `alloc` crate.

While we are at it just pull types in from `alloc` in the `prelude` - I
have no idea why we do not do this in `bitcoin`?
