At 94092aa603, we extended
MEMORY_PROFILE_ALLOC_INFO to add ActionStringOffset and
Reserved2[6] fields, that was not aware the Reserved[4]
field can be reused to have better memory profile database
size efficiency.
With the patch, PcdMemoryProfilePropertyMask|0x3 and
PcdMemoryProfileMemoryType|0xffff, the memory profile
database size can be reduced as below on my sample platform.
UefiMemoryProfileSize - 0x1597A8 -> UefiMemoryProfileSize - 0x12AB28
SmramProfileSize - 0xCF68 -> SmramProfileSize - 0xB8E8

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.

This patch enhance SMM memory profile SMM communication by using fixed
SMM communication buffer.
A new command SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET is added,
because we need to support get partial ProfileData to fixed SMM communication
buffer. If profile data is bigger than fixed SMM communication buffer,
the DXE agent need to call SMRAM_PROFILE_COMMAND_GET_PROFILE_DATA_BY_OFFSET
multiple times to get all data out.
This is designed to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS
requirement.
