InitializeApicTimer() will enable Local APIC timer interrupt. Even though we
disable CPU interrupt at the beginning and enable CPU Interrupt after debug
agent initialized completely, some Boot Service may invoke RestoreTpl () which
may enable CPU interrupt.
We should disable Local APIC timer in InitializeDebugTimer () to avoid Debug
Timer interrupt happens during debug port and debug agent initialization phase.
And enable Debug Timer interrupt after debug agent is initialized.

Now Debug Agent library uses Local APIC Timer to implement time-out mechanism.
In SMM, SMM BSP maybe not be the one in DXE phase, its local APIC timer may not
work. This fix is to initialize Local APIC timer if it doesn't work as expected
at SMM entry.

The root cause is SerialPortDebugCommunicationLib returns NULL debug port handle causing the CompressData() doesn't send the compressed data.
