REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2478

The PostCodeDebugFeaturePkg include some useful post code debug
libraries, such as get post code from status code and show it.

It provide a library PostCodeStatusCodeHandlerLib used by edk2
StatusCodeHandler.efi, used to show the post code.
It also provide a library of PostCodeMap lib, it map the status code
to post code.

V3: Modify according Eric's comments.
    Modify some bugs about dsc file when it is included.
    Update Readme.md.
V2: Delete the last empty line in PostCodeDebugFeaturePkg/Library/PostCodeMapLib/PostCodeMapLib.inf

+# Overview
+* **Feature Name:** Post Code Debug
+* **PI Phase(s) Supported:** PEI, DXE, SMM
+* **SMM Required?** Yes
+
+More Information:
+
+## Purpose
+The PostCodeDebugFeaturePkg include some useful post code debug libraries, such as get post code from status code and show it.
+This is an important capability in firmware development to get and analyze the post code.
+
+
+# High-Level Theory of Operation
+It provide a library PostCodeStatusCodeHandlerLib used by edk2 StatusCodeHandler.efi, used to show the post code.
+It also provide a library of PostCodeMap lib, it map the status code to post code.
+A library of PostCode lib is needed by platform.
+
+In the library contstructor function, PostCodeStatusCodeHandlerLib register the call back function for ReportStatusCode.
+When called, it call GetPostCodeFromStatusCode() in PostCodeMapLib to get post code from status code, and call PostCode() in PostCodeLib to show the post code.
+
+PostCodeStatusCodeHandlerLib include 3 libraries for PEI, RuntimeDxe, SMM:
+* PeiPostCodeStatusCodeHandlerLib
+* RuntimeDxePostCodeStatusCodeHandlerLib
+* SmmPostCodeStatusCodeHandlerLib
+
+## Firmware Volumes
+Linked with StatusCodeHandler.efi, and make sure put the StatusCodeHandler.efi after the ReportStatusCodeRouter.efi.
+
+## Modules
+* PostCodeStatusCodeHandlerLib
+* PostCodeMapLib
+
+## PostCodeStatusCodeHandlerLib
+This library register the call back function for ReportStatusCode, and get post code from status code, and show post code.
+
+## PostCodeMapLib
+This library provide a function to get post code from status code.
+
+## Key Functions
+* In PeiPostCodeStatusCodeHandlerLib:
+  EFI_STATUS
+  EFIAPI
+  PostCodeStatusCodeReportWorker (
+    IN CONST  EFI_PEI_SERVICES        **PeiServices,
+    IN EFI_STATUS_CODE_TYPE           CodeType,
+    IN EFI_STATUS_CODE_VALUE          Value,
+    IN UINT32                         Instance,
+    IN CONST EFI_GUID                 *CallerId,
+    IN CONST EFI_STATUS_CODE_DATA     *Data OPTIONAL
+  )
+
+* In RuntimeDxePostCodeStatusCodeHandlerLib:
+  EFI_STATUS
+  EFIAPI
+  PostCodeStatusCodeReportWorker (
+    IN EFI_STATUS_CODE_TYPE           CodeType,
+    IN EFI_STATUS_CODE_VALUE          Value,
+    IN UINT32                         Instance,
+    IN EFI_GUID                       *CallerId,
+    IN EFI_STATUS_CODE_DATA           *Data OPTIONAL
+  )
+
+* In SmmPostCodeStatusCodeHandlerLib:
+  EFI_STATUS
+  EFIAPI
+  PostCodeStatusCodeReportWorker (
+    IN EFI_STATUS_CODE_TYPE           CodeType,
+    IN EFI_STATUS_CODE_VALUE          Value,
+    IN UINT32                         Instance,
+    IN EFI_GUID                       *CallerId,
+    IN EFI_STATUS_CODE_DATA           *Data OPTIONAL
+    )
+
+* In PostCodeMapLib:
+  UINT32
+  EFIAPI
+  GetPostCodeFromStatusCode (
+    IN EFI_STATUS_CODE_TYPE           CodeType,
+    IN EFI_STATUS_CODE_VALUE          Value
+  )
+
+## Configuration
+* Link the library to StatusCodeHandler.efi.
+  Example:
+    MdeModulePkg/Universal/StatusCodeHandler/RuntimeDxe/StatusCodeHandlerRuntimeDxe.inf {
+      <LibraryClasses>
+        NULL|PostCodeDebugFeaturePkg/Library/PostCodeStatusCodeHandlerLib/RuntimeDxePostCodeStatusCodeHandlerLib.inf
+    }
+  Refer to PostCodeDebugFeature.dsc for other example.
+* Config PCD gPostCodeDebugFeaturePkgTokenSpaceGuid.PcdStatusCodeUsePostCode.
+  In platform .dsc file, need to config the type of gPostCodeDebugFeaturePkgTokenSpaceGuid.PcdStatusCodeUsePostCode.
+  Use PcdsFixedAtBuild to save binary size, and use PcdsDynamic if want to enable/disable in runtime.
+* Implemented platform's special PostCodeMapLib if needed.
+* Provide the platform's special PostCodeLib.
+* Make sure put the StatusCodeHandler.efi after the ReportStatusCodeRouter.efi.
+
+## Data Flows
+Status Code (ReportStatusCode) -> Post Code (GetPostCodeFromStatusCode).
+
+## Control Flows
+ReportStatusCode() -> PostCodeStatusCodeReportWorker() -> GetPostCodeFromStatusCode() -> PostCode()
+
+## Build Flows
+There is not special build flows.
+
+## Test Point Results
+Verify the post code shown is correct.
+
+## Functional Exit Criteria
+N/A
+
+## Feature Enabling Checklist
+* Set the PCD gPostCodeDebugFeaturePkgTokenSpaceGuid.PcdStatusCodeUsePostCode to TRUE.
+* The post code can be shown.
+
+## Common Optimizations
+* Implemented platform's special PostCodeMapLib if needed.

> +## Purpose
> 
> +The PostCodeDebugFeaturePkg include some useful post code debug
> libraries, such as get post code from status code and show it.
> 
> +This is an important capability in firmware development to get and analyze

> 
> +# High-Level Theory of Operation
> 
> +It provide a library PostCodeStatusCodeHandlerLib used by edk2
> StatusCodeHandler.efi, used to show the post code.
> 
> +It also provide a library of PostCodeMap lib, it map the status code to post
> code.
> 
> +A library of PostCode lib is needed by platform.
> 
> +
> 
> +In the library contstructor function, PostCodeStatusCodeHandlerLib register
> the call back function for ReportStatusCode.
> 
> +When called, it call GetPostCodeFromStatusCode() in PostCodeMapLib to
> get post code from status code, and call PostCode() in PostCodeLib to show
> the post code.

> 
> +PostCodeStatusCodeHandlerLib include 3 libraries for PEI, RuntimeDxe,
