Michael Brown a086f4a63b OvmfPkg: Use NestedInterruptTplLib in nested interrupt handlers 
Prevent stack underrun in the event of a timer interrupt storm in
LocalApicTimerDxe and 8254TimerDxe interrupt handlers by using the
helper functions provided by NestedInterruptTplLib.

This fixes the same problem as addressed in commit 239b50a86
("OvmfPkg: End timer interrupt later to avoid stack overflow under
load"), but does so without breaking nested timer interrupts.
