* Split //daml-foundations/daml-ghc:daml-ghc-lib
Split into multiple separate targets to improve incremental compilation
speeds.
* daml-ghc-damldoc: Remove unnecessary dependency
The target only depended on a re-export, but did also depend on the
original source of that re-export. Skipping the re-export simplifies the
dependency graph.
* Separate source dirs for daml-ghc targets
* Fix daml-ghc README
