The plain throwers allocate only a vtable pointer, but the inspection hook copied sizeof(ExceptionObject) bytes of every caught object. Copy the pointer size for the thrower cases and restore the full size afterwards.
Kept both sides in StandardExceptions.cpp: main's system_category and error_code value at offset 4 plus this PR's SceV2 types; the shared ThrowCppError and the test's ErrorCode follow the new layout. No exports overlap.

The versioned C++ library raises its own exception types:
std::__sce_v2::length_error, out_of_range, invalid_argument, runtime_error,
overflow_error, range_error, system_error, ios_base::failure and the plain
bad_function_call, bad_optional_access, bad_weak_ptr and bad_variant_access.
The message types derive from std::__sce_cxxvers::_Error_exception, which
derives from the shared std::exception. Catch clauses compiled against these
headers name the versioned types, so throwing the unversioned ones (as the
versioned _Xbad_function_call did) never reaches them.
Adds _Error_exception's constructors, destructors, what() and typeinfo; the
versioned _X* throwers, _Throw(const T&) copies and _Throw_Cpp_error; the
versioned _Syserror_map (code 0 is "success", unknown codes are
"unknown error") and _Xtime_get_ticks. _Xbad_alloc throws the shared
std::bad_alloc, as the console does. The unversioned _Throw_Cpp_error body
becomes a helper that takes the exception table.
