Add Pcd Protocol in [Depex] section and add back the constructor since PCD protocol must have been available when the entrypoint is executed.

Retrieves PCD protocol interface.
The constructor function caches the PCD_PROTOCOL pointer.
This function retrieves PCD protocol interface. On the first invocation, it
retrieves protocol interface via UEFI boot services and cache it to accelarte
further access. A module invokes this function only when it needs to access a
dynamic PCD entry.
If UefiBootServicesTableLib has not been initialized, then ASSERT ().
If PCD protocol has not been installed, then ASSERT ().
@return mPcd The PCD protocol protocol interface.
@param[in] ImageHandle The firmware allocated handle for the EFI image.
@param[in] SystemTable A pointer to the EFI System Table.
@retval EFI_SUCCESS The constructor always return EFI_SUCCESS.
