Added some docs and an example for how to use the APIC

I do believe that this could be useful when migrating from version 0.9 to version 0.11, as well as a quick way to get things going if starting from nothing.

Thank you for your contribution!

I'm not sure if we should adopt this example: This example goes way beyond what's needed to get started in setting up a small kernel with the bootloader. I'm not sure if we want this repo to serve as a place for various examples of next-steps one could take in kernel dev.

Perhaps this is better suited for the x2apic crate. Maybe it could live in its own repo entirely.

Hi there, thank you a lot for taking the time to look into this
I do understand that it might be a bit complex for a small kernel, but these were what I needed to port the 0.9 blog version to the 0.11 current version and would have liked to have had them just be available somewhere so I can read thru them. I do find that especially some of the structs that hold all the values are unnecessary for a small startup and would be more than happy to remove them along side any other future proofing

It would be nicer to look at on GitHub if this was called README.md

It doesn't have to be in this repo, but it is actually a very cool idea to have various examples of next steps. It would be very helpful. There are many people who are following https://os.phil-opp.com/, are done reading edition-2, are done reading edition-3 so far, and are figuring out how to do things rather than waiting for more stuff in edition-3. It would be very helpful if there was a place where people could share examples with each other.

Agree about various examples! It'd be nice if we could curate a list of other projects based on https://os.phil-opp.com/ that go beyond the blogs. Maybe a simple discussion thread on the original repository https://github.com/phil-opp/blog_os/discussions ?

PS: Would love to see a more minimal version of this in any way be it this repository, the blog_os project or anywhere else. This was really helpful to me. Thanks @Radu-Voinea
