Change get_gtest to link statically and remove tests from package (#261)

Currently, the `librapidsmpf` packages ship gtest/gmock library and include files, which they shouldn't.
Simplifying this down to the current version also in libcudf should fix that (i.e. by linking statically).

I would just do this to keep similar to stay similar to other rapids libraries, unless this is somehow different?

~(I think there is another small issue with `mpi_tests` and `ucxx_tests` getting shipped in `librapidsmpf` rather than `librapidsmpf-tests`, but I'll have a look at it seperately.)~
