MdeModulePkg:Add new gEdkiiVariableRuntimeCacheInfoHobGuid
This commit defines VARIABLE_RUNTIME_CACHE_INFO HOB.
The HOB is used to store the address and size of the
buffer that will be used for variable runtime service
when the PcdEnableVariableRuntimeCache is TRUE.
In following patches, when PcdEnableVariableRuntimeCache
is TRUE, VariablePei module will install a callback of
gEfiPeiMemoryDiscoveredPpiGuid to allocate needed buffer
for different type cache, unblock the buffer and build HOB.
Then VariableSmmRuntimeDxe driver will consume the
gEdkiiVariableRuntimeCacheInfoHobGuid to initialize the
variable runtime cache related content.

MdeModulePkg:Create gEdkiiVariableRuntimeCacheInfoHobGuid
Install the callback of gEfiPeiMemoryDiscoveredPpiGuid
to create gEdkiiVariableRuntimeCacheInfoHobGuid in
VariablePei module. When PcdEnableVariableRuntimeCache
is TRUE, the callback will be installed to allocate
the needed buffer for different type variable runtime
cache, unblock the buffer and build this HOB. Then the
runtime cache buffer address and size will be saved in
the HOB content.

MdeModulePkg: Refine InitVariableCache()
Refine the code logic in InitVariableCache().
In this commit, three times calling of
InitVariableCache() for different type cache are
merged into one calling. This commit is to make
the code looks cleaner and doesn't change any
code functionality.
