OvmfPkg: exclude 8254TimerDxe 

In the original three OVMF platforms, CSM_ENABLE selects the legacy timer
driver; exclude it. Instead, include LocalApicTimerDxe unconditionally
(which in turn consumes PcdFSBClock).

Background: commits c37cbc030d ("OvmfPkg: Switch timer in build time for
OvmfPkg", 2022-04-02) and 07c0c2eb0a ("OvmfPkg: fix PcdFSBClock",
2022-05-25).

Regression test: verified that the BDS progress bar still advanced at
normal speed in each platform.
