OvmfPkg: Sec: Fix SOURCE_DEBUG_ENABLE ASSERT()
The update to the LocalApicLib instances to make sure the Local APIC is
initialized before use (SVN r18595 / git commit 6d72ff7d9daf) generates an
ASSERT() when SOURCE_DEBUG_ENABLE is enabled for OVMF.
The fix is to initialize the Local APIC Timer and mask it before
initializing the DebugAgent.
