bindings: Consolidate MPI and non-MPI Fortran adios2_init and adios2_open

Combine the `bindings/Fortran/modules/{mpi,nompi}/*` sources to provide
a single definition of the modules providing the `adios2_init` and
`adios2_open` generic procedures.  Include the MPI signatures only when
ADIOS is built with MPI enabled.

Print App ID with timing infa on screen as well as write perf files with app ID, so apps in an MPMD run can be tracked. Fix array values in tasks with no step setting.

Fix race condition in LocalTimeDate()

Name them all with `_serial` and `_mpi` suffixes to distinguish them.

Update `adios2_open_old_comm` to complete the change made to
`adios2_open_new_comm` and the serial `adios2_open` by commit 1c01d05c
(Adding bindings functionality, 2018-06-27, v2.2.0^2~5).

Update the serial `adios2_open` to complete the change made to the
others by commit ff7ddfac (Enable null engine in Fortran, 2019-04-11,
v2.4.0-rc~56^2~2)

Some tests were calling `adios2_init_nompi` which is a private name
implementing one variant of the `adios2_init` generic procedure.
Use the public name instead just as applications should.

The example was calling `adios2_init_config` which is a private name
implementing one variant of the `adios2_init` generic procedure.
Use the public name instead just as applications should.

adios_reorganize: do not stay in infinite loop reading an unclosed BP file if the reading engine is BPFile, BP3, File or the default (picked by empty string). Instead, explain what's going on and finish.

Fix memory leak from CompressZFP.

table: Enable engine without MPI by cleaning up sub-adios APIs

Allow setting absolute paths for CMAKE_INSTALL_BINDIR

Fix end condition when iterating through `if_nameindex` array.
Add missing resource free operations in error conditions.

Unfortunately the Clang Memory Sanitizer does not recognize that
`if_nameindex` initializes the array behind the pointer it returns
and complains on the first dereference that it is uninitialized.
Suppress the Memory Sanitizer for this function.

Now that we manage table's sub-adios through the core API we can access
the core ADIOS constructor that accepts the Comm abstraction instead of
a raw MPI_Comm.  We can use `Comm::World()` instead of `MPI_COMM_WORLD`.
This allows us to enable the Table engine even when ADIOS is built
without MPI.

Avoid using the public C++11 bindings API from the core implementation.
