Include type info for only some exprs in HIE files
This commit relinquishes some some type information in `.hie` files in exchange for better performance. See #16233 for more on this. Using `.hie` files to generate hyperlinked sources is a crucial milestone towards Hi Haddock (the initiative to move Haddock to work over `.hi` files and embed docstrings in those). Unfortunately, even after much optimization on the Haddock side, the `.hie` based solution is still considerably slower and more memory hungry than the existing implementation - and the @.hie@ code is to blame. This changes `.hie` file generation to track type information for only a limited subset of expressions (specifically, those that might eventually turn into hyperlinks in the Haddock's hyperlinker backend).
