MdeModulePkg: Extend memory profile definitions for memory leak detection

Browse Source 
Current memory profile feature:
1. Shows which line of code calls gBS->AllocateXXX(). But most entries
are from MemoryAllocationLib.
2. Records at the start.
3. Records all modules.

Enhanced memory profile feature:
1. User can know which line of code calls AllocateXXX() API instead of
gBS->Allocate().
2. User can know which line of code calls a specific API that will call
AllocateXXX().
3. User can know total memory allocated by a specific line of code.
4. User can configure to record single module.
5. User can configure when to enable recording.
6. User can know RVA<->Symbol (Function, Source, Line).

For the enhanced memory profile feature,
1. Extend MEMORY_PROFILE_DRIVER_INFO to include PdbString.
2. Extend MEMORY_PROFILE_ALLOC_INFO to include ActionString.
3. Extend MEMORY_PROFILE_ACTION to indicate action in memory allocation
lib and user defined action.
4. Extend memory profile protocol to include GetRecordingState/
SetRecordingState/Record.
5. Define SMM memory profile protocol.
6. Extend PcdMemoryProfilePropertyMask to support disable recording at
the start.
7. Introduce new PCD PcdMemoryProfileDriverPath to control which drivers
need memory profile data.
