MdeModulePkg/XhciDxe: Add boundary check for TRB ring allocation
According the Xhci Spec, TRB Rings may be larger than a Page, however they
shall not cross a 64K byte boundary, so add a parameter to indicate
whether the memory allocation is for TRB Rings or not. It will ensure the
allocation not crossing 64K boundary in UsbHcAllocMemFromBlock if the
memory is allocated for TRB Rings.
