•	Make access to PcdDxeIplSwitchToLongMode to Ia32 specific code.
•	Introduce another feature flag named PcdDxeIplBuildShareCodeHobs to define whether to build hobs to DXE core to share code.
•	Remove the #progma bug

Routine Description:
Creates architecture-specific HOBs.
Note: New parameters should NOT be added for any HOBs that are added to this
function. BspStore is a special case because it is required for the
call to SwitchStacks() in DxeLoad().
Arguments:
BspStore - The address of the BSP Store for those architectures that need
it. Otherwise 0.
Returns:
EFI_SUCCESS - The HOBs were created successfully.
