Subject: [RFC] BZ 1772 MdeModulePkg: Transfer reset data

HI,

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1772

Before the ResetData of ResetSystem is limit by ResetType and ResetStatus. As the Uefi spec update to 2.8, there is no limit any longer.
Here we introduce a new API ResetSystemWithSubtype to transfer a null string and GUID data with all ResetType to reset system.
It is useful for capsule update to get a specific GUID to do some special operation with specific phase. That can be implemented in platform code thru Reset Notify protocol.
Here is the guids:
gEdkiiCapsuleArmedResetGuid            = {0xc6b4eea7, 0xfce2, 0x4625, {0x9c, 0x4f, 0xc4, 0xb0, 0x82, 0x37, 0xae, 0x23}}
gEdkiiCapsuleUpdateCompleteResetGuid   = {0x5d512714, 0xa4df, 0x4e46, {0xb6, 0xc7, 0xbc, 0x9f, 0x97, 0x9d, 0x59, 0xa0}}

Thanks,
Zhichao

It is an recommended feature change. But the specific function isn't implemented with any platform yet. So it wouldn't affect any section of the edk2.
And it changed a lot of platform dsc files(or module package dsc files) in both edk2 and edk2-paltform. That may take time for the review work.
I think it is fine if this feature doesn't catch the end-line of the software-freeze.

Thanks,
Zhichao
