Move GetStoragePartitionConfig to SecurityPrincipal interface
Refactor storage partition configuration access by introducing
GetStoragePartitionConfig() on the SecurityPrincipal interface and
removing it from SiteInstance.
Update all call sites to access the storage partition configuration
through GetSecurityPrincipal().GetStoragePartitionConfig() instead of
directly calling GetStoragePartitionConfig() on SiteInstance.
This CL also adds unit test to ensure that the storage partition config
remains unchanged once accessed, preventing accidental changes that
could violate security boundaries.
Most of existing functionality remains unchanged. The
StoragePartitionConfig consistency verification now triggers on any call
to GetSiteInfo()/GetSecurityPrincipal() before SetSiteInfoInternal()
assigns the final SiteInfo, rather than only when the
StoragePartitionConfig is explicitly accessed. This is a broader check
than before, but it avoids the need to plumb an extra flag through
SecurityPrincipal/SiteInfo to track whether GetSecurityPrincipal() was
used specifically to read the StoragePartitionConfig.
