haddock: Build haddock-api and haddock-library using hadrian

We build these two packages as regular boot library dependencies rather
than using the `in-ghc-tree` flag to include the source files into the haddock
executable.

The `in-ghc-tree` flag is moved into haddock-api to ensure that haddock built
from hackage can still find the location of the GHC bindist using `ghc-paths`.

Addresses #24834

This causes a metric decrease under non-release flavours because under these
flavours libraries are compiled with optimisation but executables are not.

Since we move the bulk of the code from the haddock executable to the
haddock-api library, we see a metric decrease on the validate flavours.

Metric Decrease:
    haddock.Cabal
    haddock.base
    haddock.compiler
