x86/paravirt: Move pv_native_*() prototypes to paravirt.c

The only reason the pv_native_*() prototypes are needed is the complete
definition of those functions via an asm() statement, which makes it
impossible to have those functions as static ones.

Move the prototypes from paravirt_types.h into paravirt.c, which is the
only source referencing the functions.
