Somehow using a custom build_ext subclass always triggered a failing
rebuild when testing:

Therefore we resort to only setting the CC and CXX variables to the
C++ compiler. Note that one cannot use "ccache c++" for CXX.
With the default build_ext the problem vanishes.
CC is the C compiler. CXX is the C++ compiler. Setuptools will
use the C++ compiler for C++ code. Hence it is vital to set that
correctly. If not set the default C++ compiler will be used.
Unfortunately it will use the first string as the CXX compiler and
hence we need to strip ccache. Fortunately it used CC for the
compilation and that works with gcc as well.
It is used verbatim in setup.py in the list that specifies the linker
flage. Hence it needs to comma separted instead of using a semicolon
as separator.
We also rename it to SETUP_PY_LINKAGE to indicate where it is used.
Closes#2947
Add support for UDA values items when constructing DeckKeywords from
DeckValues. This is needed when constructing DeckKeywords
from Python. For example WCONPROD has UDA value argument for the oil
rate.
this means getting rid of the Opm::filesystem namespace
and directly using std::filesystem, as well as dropping
some of the compat code for the tr filesystem.
we still need the FileSystem.hpp/cpp files though as unique_path
is not part of std::filesystem.
