1) Remove dependency on the UEFI Boot Services Table Library so the gBS, gST, and gImageHandle symbols will not be automatically linked into an SMM Driver that uses this library.
2) Remove redundant include of <PiDxe.h>
3) Clean up constructor to use InSmm() library function instead of duplicating logic.

Remove constructor from this library. This library already has SMM CPU I/O 2 in its [Depex], so any module using this library will not be dispatched until the SMM CPU I/O 2 Protocol is installed into the SMM handle database and also copied into the SMM Services Table.
The worker functions in this library have also been updated to simply use the instance of the SMM CPU I/O 2 Protocol that is present in the SMM Services Table.
The dependency on the UEFI Boot Services Table Library has also been removed so the gBS, gST, and gImageHandle symbols will not be automatically linked into an SMM Driver that uses this library.

Update DXE Core to be compatible with PI 1.2 SMM Drivers.
PI 1.2 SMM Drivers are allowed to call UEFI/DXE services and Protocols from the entry point of the PI 1.2 SMM Driver. These UEFI/DXE services and Protocols may directly or indirectly calls the UEFI Boot Services RaiseTPL() and RestoreTPL(). These UEFI Boot Services use the CPU Architectural Protocol to enable interrupts if the TPL level is below TPL_HIGH_LEVEL and enable interrupts of the TPL is at TPL_HIGH_LEVEL. Interrupts should be masked while executing SMM drivers, so if a direct or indirect call to the UEFI Boot Service RestoreTPL() would enable interrupts, then an interrupt could be incorrectly delivered in SMM context.
The solution is for the DXE Core to register for the PI 1.2 SMM Base2 Protocol. If that protocol is present in the platform, then the DXE Core can use the SMM Base 2 Protocol's InSmm() function to determine if the platform is currently executing in SMM content. If the current context is in SMM, then do not allow any requests to be forwarded to the CPU Architecture Protocol to enable interrupts.

Do not set gBS to NULL when the ExitBootServices event notification for the UEFI Runtime Lib is executed.
There is no guarantee that the ExitBootServices notification function from this lib will be the last ExitBootServices notification function registered by a module that uses the UEFI Runtime lib. If additional ExitBootServices notification functions require the use of gBS, then setting to NULL will break those additional ExitBootServices notification functions.

Pass the correct TokenNumber into a CallbackOnSet notification function. The value being passed in was off by 1.
This would not normally cause an issue because the correct notification function was being called. There is only an issue if the same notification function is being used for multiple tokens, and the notification function needs to use the TokenNumber parameter to determine which token setting caused the callback function to be called.
Update the logic so the CallbackOnSet notification functions are not called with the internal PCD database lock in the acquired state. This allows other PCD Get/Set operations to be performed from within a CallbackOnSet notification.
Update logic so the PCD database lock is not left in the acquired state when SetWorker() returns EFI_INVALID_PARAMETER.
