REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1853 Code change form Mu project: https://github.com/microsoft/mu_basecore/blob/release/201903/ MdeModulePkg/Universal/CapsulePei/UefiCapsule.c#L801 Separate the capsule check function from GetCapsuleDescriptors to AreCapsulesStaged. The original one is unclear. Avoid querying the capsule variable twice. Use a fixed array to cache the SG list during count the number of SG list. Then allocate memory buffer to save the SG list from array. Using MemoryAllocationLib instead of memory function in Pei services.
