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.
