MdeModulePkg/XhciDxe: Use Performance Timer for XHCI Timeouts

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2948

XhciDxe uses the timer functionality provided by the
boot services table to detect timeout conditions. This
breaks the driver's ExitBootServices call back, as
CoreExitBootServices halts the timer before signaling
the ExitBootServices event. If the host controller
fails to halt in the call back, the timeout condition
will never occur and the boot gets stuck in an indefinite
spin loop. Use the free running timer provided by
TimerLib to calculate timeouts, avoiding the potential
hang.
