RestoreTPL called while at TPL_HIGH_LEVEL unconditionally enables
interrupts even if called in interrupt handler. That opens a window while
interrupt is not completely handled but another interrupt could be
accepted.
If a VM starts on a heavily loaded host hundreds of periodic timer
interrupts might be queued while vCPU is descheduled (the behavior is
typical for a Xen host). The next time vCPU is scheduled again all of them
get delivered back to back causing OVMF to accept each one without
finishing a previous one and cleaning up the stack. That quickly results
in stack overflow and a triple fault.
Fix it by postponing sending EOI until we finished processing the current
tick giving interrupt handler opportunity to clean up the stack before
accepting the next tick.

[lersek@redhat.com: add BZ ref; rewrap msg to silence PatchCheck.py]
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.
