[lld-macho][nfc] Give every SyntheticSection a fake InputSection Previously, it was difficult to write code that handled both synthetic and regular sections generically. We solve this problem by creating a fake InputSection at the start of every SyntheticSection. This refactor allows us to handle DSOHandle like a regular Defined symbol (since Defined symbols must be attached to an InputSection), and paves the way for supporting `__mh_*header` symbols. Additionally, it simplifies our binding/rebase code. I did have to extend Defined a little -- it now has a `linkerInternal` flag, to indicate that `___dso_handle` should not be in the final symbol table. I've also added some additional testing for `___dso_handle`.
