Uno bridge msvc-x86_64: Fix EH memory and addressing issues

Rewrite of 32-Bit-Code to work under 64 Bit:
To use the 32 Bit offset values in the ExceptionType we have to
allocate a single allocation block and use it for all code and data.
All offsets inside this area are guaranteed to be in 32 bit address
range. So we have to calc total memory allocation size for D-tor,
C-Tors, ExceptionType and type_info. ExceptionType is allocated via
placement new operator to locate everything inside our mem block.

There is one caveat: Struct type_info is kept in a map and was
referenced from class ExceptionType. Therefore type_info now is also
member of ExceptionType and can be referenced via 32 bit offset.
