Add compilers bibliography apprendix

[spastorino]

There's already a Rust Bibliography appendix, I think it would be great to start a compilers bibliography appendix that may help give some background to better understand the compiler.

For instance, we could start by adding some of these resources from Rust Programming Language Community Server #lang-dev channel.

I like the idea. Perhaps a section at the end of Background Appendix with extra reading?

@mark-i-m yes, I think that would be fine.

@spastorino The link appears to be broken... Do you happen to know what was there...

Also, in the future, perhaps it would be best not to post links to discord?
