OvmfPkg/8254TimerDxe: Update to make it build for OVMF REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1496 This commit will remove the IntelFrameworkPkg DEC file dependency in the driver INF file. A new GUID has been updated for the INF file. Corresponding changes have been made in OVMF DSC files as well in order to verify the build. Please note that a subsequent commit (final patch of the series) will: A) Add OvmfPkg/8254TimerDxe driver in OVMF FDF files; B) Remove the consumption of PcAtChipsetPkg/8254TimerDxe driver in OVMF DSC/FDF files.

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.
