PrmPkg: Enforce stricter types

PrmPkg: Enforce stricter types

Makes the following changes to enforce stricter types:

1. PrmPkg/PrmConfigDxe

   The function PrmConfigEndOfDxeNotification () is used as a notify
   function (of type EFI_EVENT_NOTIFY), however it has a return type
   of EFI_STATUS whereas the return type should actually be VOID.

2. PrmPkg/PrmLoaderDxe

   Updates the following types to be more accurate than were allowed
   in the VS compiler:
   * 3rd actual argument given to GetModuleContextBuffers () is
     explicitly marked as CONST PRM_MODULE_CONTEXT_BUFFERS **

   * 3rd actual argument given to GetContextBuffer () is
     explicitly marked as CONST PRM_CONTEXT_BUFFER **

   * PrmLoaderEndOfDxeNotification () return type is changed to VOID
     to align with the EFI_EVENT_NOTIFY type

3. PrmPkg/Application/PrmInfo

   Updates the following types to be more accurate than were allowed
   in the VS compiler:
   * SHELL_STATUS in ParseParameterList () is now EFI_STATUS

   * 3rd actual argument given to GetModuleContextBuffers () is
     explicitly marked as CONST PRM_MODULE_CONTEXT_BUFFERS **

   * 3rd actual argument given to GetContextBuffer () is
     explicitly marked as CONST PRM_CONTEXT_BUFFER **
