rename types.h to "pmacc_types.hpp`

[psychocoderHPC]

Currently the global PMacc definitions are places in a C header files.
we should:

• rename it to a C++ header (file ending .hpp)
• change the name to pmacc_types to avoid conflicts with system headers

yeees pls! :)

Noooo! Introduce more C header files and give them names of existing standard C header files!!!

Next step: try to get PRs merged upstream in glibc renaming those standard headers to "resolve conflicts" 🎸

@psychocoderHPC just a side note: we will not install libPMacc without a prefix directory, since this is messy and will always collide somewhere with third parties.

We can still rename the file, but users of PMacc should include it in a <pmacc/some_header.hpp> and <pmacc/pmacc_types.hpp> way.

Example install in --prefix=/usr (as seen in boost or libSplash):

# headers
/usr/include/pmacc/some_header.hpp
/usr/include/pmacc/memory/even_more_headers.hpp
# ...
