Hadrian: refactor GMP in-tree build support (#17756)
* Hadrian doesn't use integer-gmp/config.mk file anymore to determine if
building GMP in-tree is required.
"config.mk" is created by Cabal when the integer-gmp package is
configured and this file is still untracked by Hadrian. This led to a
tricky configure "race" because "config.mk" is built by the
"setup-config" rule, but this rule is also used to find dependencies,
in particular the "ghc-gmp.h" header, but the creation of this file
was depending (without being tracked) on "config.mk".
Now Hadrian only builds in-tree GMP if `--with-intree-gmp` is passed
to the top-level configure script.
* in-tree GMP isn't built once for all in a fixed stage (Stage1)
anymore. It is built per stage which is required if we build a
cross-compiler
* switching between in-tree and external GMP is now supported without
having to clean the build directory first.
* "wrappers.c" now includes "ghc-gmp.h" instead of "ghc.h". It
helps ensuring that the build system generates "ghc-gmp.h".
* build in-tree GMP in "<root>/stageN/gmp/gmpbuild" and produce useful
artefacts (libgmp.a, gmp.h, objs/*.o) in "<root>/stageN/gmp"
