Brief Description

There are a number of synchronization primitives in iceoryx2-pal used throughout all layers of iceoryx2.

1. Atomics
2. Lazy
3. Spin

To adhere to the architecture, crates should not be depending directly on iceoryx2-pal, so these primitives should be exposed via a crate in iceoryx2-bb.

Once changed, all crates should access these primitives from the new location.

1. Usages of atomics throughout iceoryx2
2. Usages of spin in the bare metal example
