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.

AreCapsulesStaged do not need to return the status, only boolean
result is useful. So directly return a boolean value.
Cannot initialize the variable at its definition.
GetScatterGatherHeadEntries: use allocated buffer instead of fixed
array to handle the condition which the SG list is larger then the
array size.
Remove API specifier AreCapsulesStaged and GetScatterGatherHeadEntries
because they are internal used.
Fix some coding style issues.
