In CPhysicalGeometry.cpp, instances of derived classes are delete'd via CMeshReaderFVM pointers. Without a virtual destructor, destructors of members added by these derived classes are not called. With respect to e.g. the std::vector members of CCGNSMeshReaderFVM, this leads to memory leaks.

This helps to avoid memory leaks and double frees from the respective COptionActDisk instances, and allows to check that identical marker lists were supplied.

Steps to reproduce the underlying issue
Compile SU2 with Clang and
-fsanitize=address
(and possibly-fno-omit-frame-pointer
), and run the testcases as usual. AddressSanitizer warnings appear in the output (if any).So far, only the tests in serial_regression.py have been analyzed.

#2211 and #2213 have been detected in the same way, but I'm not sure how to properly fix them.
