Refactor runtime interpreter code
In #14335 we want to be able to use both the internal interpreter (for the plugins) and the external interpreter (for TH and GHCi) at the same time. This patch performs some preliminary refactoring: the `hsc_interp` field of HscEnv replaces `hsc_iserv` and is now used to indicate which interpreter (internal, external) to use to execute TH and GHCi. Opt_ExternalInterpreter flag and iserv options in DynFlags are now queried only when we set the session DynFlags. It should help making GHC multi-target in the future by selecting an interpreter according to the selected target.
