UefiCpuPkg/PiSmmCpuDxeSmm: Add logic to support semaphore type.

Browse Source 
V4 changes:
1. Serial console log for different threads when program register table.
2. Check the AcpiCpuData before use it to avoid potential ASSERT.

V3 changes:
1. Use global variable instead of internal function to return string for register type
   and dependence type.
2. Add comments for some complicated logic.

V1 changes:
Because this driver needs to set MSRs saved in normal boot phase, sync
semaphore logic from RegisterCpuFeaturesLib code which used for normal boot phase.

Detail see below change for RegisterCpuFeaturesLib:
