Use `.hie` files for the Hyperlinker backend (#977)
# Summary
This is a large architectural change to the Hyperlinker.
* extract link (and now also type) information from `.hie` instead
of doing ad-hoc SYB traversals of the `RenamedSource`. Also
adds a superb type-on-hover feature (#715).
* re-engineer the lexer to avoid needless string conversions. By going
directly through GHC's `P` monad and taking bytestring slices, we
avoid a ton of allocation and have better handling of position
pragmas and CPP.
In terms of performance, the Haddock side of things has gotten _much_
more efficient. Unfortunately, much of this is cancelled out by the
increased GHC workload for generating `.hie` files. For the full set of
boot libs (including `ghc`-the-library)
* the sum of total time went down by 9-10% overall
* the sum of total allocations went down by 6-7%
# Motivation
Haddock is moving towards working entirely over `.hi` and `.hie` files.
This change means we no longer need the `RenamedSource` from
`TypecheckedModule` (something which is _not_ in `.hi` files).
# Details
Along the way a bunch of things were fixed:
* Cross package (and other) links are now more reliable (#496)
* The lexer tries to recover from errors on every line (instead of at CPP
boundaries)
* `LINE`/`COLUMN` pragmas are taken into account
* filter out zero length tokens before rendering
* avoid recomputing the `ModuleName`-based `SrcMap`
* remove the last use of `Documentation.Haddock.Utf8` (see #998)
* restructure temporary folder logic for `.hi`/`.hie` model
