Michael Kubacki e10c776487 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 **

Michael Kubacki 0797989c5d PrmPkg: Remove ALLOCATE_CONTEXT_BUFFER_IN_FW build flag
The POR is firmly to use an OS allocated context buffer now so the
build flag that allows firmware to allocate the context buffer
is removed along with supporting code.

Michael Kubacki e846797662 PrmPkg: Add ALLOCATE_CONTEXT_BUFFER_IN_FW build option
There's currently two approaches being considered for how to allocate the
context buffer passed to PRM handlers:

1. The context buffer is allocated and populated in firmware. As such, the
   FW converts all pointers internal to the buffer to virtual memory
   addresses at the virtual address change event. A single context buffer
   pointer is given to the OS via the PRM ACPI table and the OS converts
   this single physical address to a virtual address when it passes the
   context buffer as a pointer to PRM handlers.

2. The context buffer is allocated and populated in the OS. The OS gets
   all the information needed to populate the context buffer from other
   pre-existing resources (mainly physical addresses in the PRM ACPI
   table). The OS converts all the physical addresses to virtual addresses,
   allocates the context buffer instances, and fills in the information.
   The OS passes the context buffer virtual address to PRM handlers.

The prior behavior was (1). The current POR behavior has moved to (2).
Until (2) is used more widely, it can be kept around with fairly minimal
overhead via a build flag in a few places.

So the default behavior is now (2) (the expected permanent behavior) with
(1) easily enabled by defining "ALLOCATE_CONTEXT_BUFFER_IN_FW" in the
compiler defined macros. A DSC define was added in PrmPkg.dsc to set this
compiler macro in the package  build.

At some point in the future, all code (and some peripheral code)
surrounded with this build flag can be removed if (2) is fully
decided upon.

Michael Kubacki 3f7af17c6b PrmPkg/PrmConfigDxe: Add initial driver
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3812

This driver serves as a generic PRM configuration driver. Its primary
role is to prepare PRM resources published by PRM module configuration
libraries for OS runtime. As such, it locates all PRM Configuration
Protocol instances and consumes the information to ready those resources.

For example, set runtime memory attributes on MMIO ranges and convert
physical addresses to virtual addresses in PRM buffers.
