[Linux][GDBJIT] Fix crashes related with locals debug info generation (dotnet/corecl...

* [GDBJIT] Fix several issues related with generation debug info for locals:
* Fix crash on generics static
* Add support of pointer type
* Fix incorrect processing of classes when we have several locals with the same class type

* Move gdbjit.cpp from VM_SOURCES_DAC_AND_WKS_COMMON to VM_SOURCES_WKS
