Jextract used to store several information in the form of layouts attributes. After some analysis, it turned out that in all cases, the use of layout attributes was not necessary, and it was really driven by the fact that jextract was, in certain places, using `MemoryLayout` as its main internal representation, instead of using the more flexible `Declaration`/`Type` APIs. Unfortunately, updating `RecordLayoutComputer` to work on `Declaration` rather than `MemoryLayout` caused changes in several part of the jextract parsing frontend.

I've dropped several now redundant overloads (so the size of the generated bindings should be smaller). There's also an additional piece of code which is used to emit typedef for common C primitive types such as `C_INT` and the likes (since the layouts for these are no longer in `CLinker`).
