Run all tests under valgrind

[msimberg]

#795 and #797 added a few tests to be run under valgrind in CI. The changes in #795 makes it possible to opt-in tests to be tested under valgrind. We should expand the list of tests to improve our coverage. This is another issue probably best tackled roughly module by module (or even test by test). Below is a list of modules (and the examples directory) that are fully covered by valgrind:

• [x] async_combinators (module removed in #774)
• [ ] async_cuda

#1042 enabled valgrind testing for all modules. The only ones not tested are the MPI and CUDA/HIP modules.
