tdf#128345 Move unit tests from sd to chart2 and improve them

a) The unit tests are about charts and therefore it is more natural to
have them in module chart2.
b) The file name of the chart in the pptx package is generated with a
static counter. Therefore the name depends on whether there have
been previous savings. Module chart2 has a method, that ignores the
number and takes the first matching file. Using that makes the tests
more stable and allows to fix the static counter without need to
adjust the tests.
c) I have put them into a new test suite, which I have started
recently. The other test suites are already hudge.
So this patch depends on commit
74be8bb787a44464957e5d3105c8de6d36e81b4a
d) I have made the paths in the tests independent of the naming
conventions which LibreOffice uses for styles and definitions.
e) I have split the tests in export and import.
