Unlike the InstallMultipleProtocolInterfaces() boot service, which takes
an (EFI_HANDLE*) as first parameter, the
UninstallMultipleProtocolInterfaces() boot service takes an EFI_HANDLE as
first parameter.
This is an actual bug. It must have remained hidden until now because it's
on an error path. Fix the UninstallMultipleProtocolInterfaces() call.

XenHypercallLib has two clients at the moment: XenBusDxe and
XenConsoleSerialPortLib. Currently, when XenBusDxe starts on a non-Xen X86
platform (ie. as part of OVMF not running on Xen), the X86XenHypercallLib
instance built into it fails to initialize, which triggers an ASSERT() in
auto-generated code.
Instead, let's call XenHypercallIsAvailable() in the driver's entry point,
and exit cleanly when the driver is started on a non-Xen platform.
Modify the constructor of XenConsoleSerialPortLib similarly; we shouldn't
proceed if Xen is not available. In practice this check should never fail,
because XenConsoleSerialPortLib is only used on ARM, and
ArmXenHypercallLib is always available; but nonetheless we should be
pedantic.

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.
