[MS Demangler] Print calling convention inside parentheses.

For function pointers, we would print something like

int __cdecl (*)(int)

We need to move the calling convention inside, and print

int (__cdecl *)(int)

This patch implements this change for regular function pointers as
well as member function pointers.
