Adds a new function called GetCpuMaxLogicalProcessorNumber() to
return the number of maximum CPU logical processors (currently
gUefiCpuPkgTokenSpaceGuid.PcdCpuMaxLogicalProcessorNumber).
This allows the the mechanism used to retrieve the CPU maximum
logical processor number to be abstracted from the logic that
needs the value.

There's currently two library instances:
1. SmmCpuFeaturesLib
2. SmmCpuFeaturesLibStm
There's two constructor functions:
1. SmmCpuFeaturesLibConstructor()
2. SmmCpuFeaturesLibStmConstructor()
SmmCpuFeaturesLibConstructor() is called by
SmmCpuFeaturesLibStmConstructor() since the functionality in that
function is required by both library instances.
The declaration for SmmCpuFeaturesLibConstructor() is embedded in
"SmmStm.c" instead of being declared in a header file. Further,
that constructor function is called by the STM specific constructor.
This change moves the common code to a function called
CpuFeaturesLibInitialization() which is declared in an internal
library header file "CpuFeaturesLib.h". Each constructor simply
calls this function to perform the common functionality.
Additionally, SmmCpuFeaturesLibConstructor() is moved from
SmmCpuFeaturesLibNoStm.c into a instance-specific file allowing
SmmCpuFeaturesLibNoStm.c to contain no STM implementation agnostic
to a particular library instance.

FinishSmmCpuFeaturesInitializeProcessor() is a multi-instance
internal library function that is currently not declared in a
header file but embedded in "SmmCpuFeaturesLib.c".
This change cleans up the declaration moving it to a new header
file "CpuFeaturesLib.h" and removing the local declaration in
"SmmCpuFeaturesLib.c".
