Break up `Settings` into smaller structs
As far as I can tell, the fields within `Settings` aren't *intrinsicly* related. They just happen to be initialized the same way (in particular prior to the rest of `DynFlags`), and that is why they are grouped together. Within `Settings`, however, there are groups of settings that clearly do share something in common, regardless of how they anything is initialized. In the spirit of GHC being a library, where the end cosumer may choose to initialize this configuration in arbitrary ways, I made some new data types for thoses groups internal to `Settings`, and used them to define `Settings` instead. Hopefully this is a baby step towards a general decoupling of the stateful and stateless parts of GHC.
