MT#59962 XMLRPC2DI: make general members static

There is only one instance of XMLRPC2DI API,
hence only one possible value for a list of
class members, such as:
- XML RPC port for DI
- XML RPC DI server
- variable, which defines, if that's configured

Additionally fixes:

    Uninitialized pointer field (UNINIT_CTOR)
    uninit_member: Non-static class member XMLRPCPort
    is not initialized in this constructor nor in any functions that it calls.
