Fix MPI Signal Handling on Perlmutter (#3029)
* Fix: `MPI_CXX_BOOL` -> `MPI_BYTE`
C99 types were aded in MPI-2.2, while Cray's MPICH fork in version
8.1.13 defines `MPI_CXX_BOOL` to `MPI_DATATYPE_NULL` on Perlmutter.
We could use `MPI_C_BOOL`, which is technically a `_Bool` from
[<cstdbool>](https://en.cppreference.com/w/cpp/header/cstdbool)
(deprecated: C++17; removed: C++20) - or we simply do a static
assert on `sizeof(bool)` and communicate as a `MPI_BYTE` or
`MPI_CHAR`.
* Signals: Do no MPI Comms if none is configured
* Docs: Link and Explain Allowed Signal Values
* Review Comments & Style
