Description

In the recently merged op-rbuilder code, primitives are defined inside the builder in a [primitives module(https://github.com/base/node-reth/blob/main/crates/builder/op-rbuilder/src/primitives/mod.rs).

This ticket is to split out primitives into the shared primitives crate.

The builder's Bundle Type should be de-duplicated since it already exists in the base-bundles crate here.
