hadrian: Need builders needed by Cabal Configure in parallel

Because of the use of withStaged (which needs the necessary builder)
when configuring a package, the builds of stage1:exe:ghc-bin and
stage1:exe:ghc-pkg where being linearised when building a specific
target like `binary-dist-dir`.

Thankfully the fix is quite local, to supply all the `withStaged`
arguments together so the needs can be batched together and hence
performed in parallel.

Fixes #22093
