This adds initial support for reading the SDI content from InnoDB tablespace files, but doesn't yet use the SDI for anything other than a new space-sdi-json-dump mode (similar to ibd2sdi), which can be used to confirm that SDI is successfully read. Subsequent work will refactor the Innodb::DataDictionary class to be able to make use of SDI.
