Auto merge of #70536 - Centril:rustc-middle, r=eddyb

Rename `librustc` to `librustc_middle`

Here we rename `librustc` to `librustc_middle`.

This crate is not nearly as large or central as it was previously and so it doesn't make much sense to give it such a central name as `librustc` ("the entry point to the compiler"). Moreover, there is already a `rustc` crate which is has the actual `fn main` of `rustc`, so having `librustc` is confusing relative to that.
