There isn't really any benefit to having a bunch of tiny files each of which defiles a single error. This PR moves all error types from dfx-core/errors/identity/*.rs to dfx-core/errors/identity.rs. This PR makes no changes to the error types themselves, only moves them.
I'll be following up with changes that split up FsError into per-method error types, which will add some new error types, so I wanted to do this first.
