 Hadrian: simple targets for building libraries and executables

 This patch introduces (phony) build targets of the form

     (1) stage<N>:<lib>:<name>   (e.g: stage1:lib:Cabal)
     (2) stage<N>:<exe>:<name>   (e.g: stage2:exe:ghc-bin)

 where (1) builds the given library with the stage N compiler and (2)
 builds the given executable with the stage N-1 compiler. This patch may
 be generating too many such targets but it's a first stab that we can
 refine.

 This fixes #15949.

 Test Plan: hadrian/build.sh stage1:exe:ghc-bin
