gh-93584: Make all install+tests targets depends on all (GH-93589)

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.
