[3.11] gh-93584: Make all install+tests targets depends on all (GH-93589) (GH-93603)
All install targets use the "all" target as synchronization point to
prevent race conditions with PGO builds. PGO builds use recursive make,
which can lead to two parallel `./python setup.py build` processes that
step on each others toes.
"test" targets now correctly compile PGO build in a clean repo.
