Add a tiny bytes::Bytes like implementation

[bantonsson]

What does this PR do?

Adds a tiny bytes::Bytes like implementation for having multiple byte slices pointing into the same slice.

Motivation

The implementation in bytes::Bytes does not allow us to use the mapped memory types in the ipc crate, and implementing support for such types in the original crate is a not an option, since it is non trivial and there is a large amount of functionality that doesn't map well to the mapped memory.

Additional Notes

Jira ticket: APMS-1330

How to test the change?

There are tests.
