Ovmf/Xen: refactor XenBusDxe hypercall implementation
This refactors the Xen hypercall implementation that is part of the
XenBusDxe driver, in preparation of splitting it off entirely into
a XenHypercallLib library. This involves:
- removing the dependency on XENBUS_DEVICE* pointers in the XenHypercall()
prototypes
- moving the discovered hyperpage address to a global variable
- moving XenGetSharedInfoPage() to its only user XenBusDxe.c (the shared info
page is not strictly part of the Xen hypercall interface, and is not used
by other expected users of XenHypercallLib such as the Xen console version
of SerialPortLib
- reimplement XenHypercall2() in C and move the indexing of the hyperpage
there; the existing asm implementations are renamed to __XenHypercall2() and
invoked from the new C implementation.
