Remove PolarisMetaStoreSession from FileIOFactory/FileIOUtil in favor…

… of CallContext

This appeared to be some leaky divergence that occurred after CallContext had been
removed, but PolarisMetaStoreSession really is only a low-level implementation detail
that should never be handled by BasePolarisCatalog/FileIOFactory.

This plumbs CallContext explicitly into the FileIOFactory and FileIOUtil methods and
thus removes a large source of CallContext.getCurrentContext calls; now the threadlocal
doesn't have to be set at all in BasePolarisCatalogTest.
