Since PcdPropertiesTableEnable is used by the DXE Core (in the InstallPropertiesTable() function, which runs at End-of-Dxe), we must also change the PcdLib class resolution for that module, from the default BasePcdLibNull to DxePcdLib. Traditionally we've considered the DXE Core to be incapable of accessing dynamic PCDs -- the PCD PPI is not available any longer to the DXE Core, and the PCD Protocol is not available to it *yet*. There are exceptions however: if the DXE Core can ensure, by whatever means, that the PCD Protocol *is* available, then DxePcdLib will just work (the latter even lists DXE_CORE as an allowed client module type). Namely, DxePcdLib looks up the PCD Protocol dynamically, on the first library call that actually needs it (for accessing a dynamic PCD); the lookup doesn't occur in a library constructor. And because the DXE Core fetches PcdPropertiesTableEnable at End-of-Dxe, the PCD Protocol is definitely available then. In addition, we change the default value of PcdPropertiesTableEnable from the inherited TRUE to FALSE. It makes no difference at this point (our runtime DXE drivers are not built with the required 4KB section alignment anyway), but it's better to be clear about this. The properties table feature requires OS compatibility, and it breaks Windows 7 minimally. Therefore the default should be FALSE.
