[roll] Roll fuchsia [ftl] Add diagnosis output to volume extractor. Adds a diagnosis section for analyzing known issues in an FTL. This makes it easy to reach inside the FTL and check on various conditions to identify known symptoms of issues that have been found to corrupt an FTL volume. Including a check for Partial Page Writes, as well as specifically checking for them when the fix has already been applied. Also looks for vpage mapping collisions to identify Premature Block Recycle. A couple of problems have just had their logging adjusted to make spotting the issue more clear, such as the failed read during load time, and also a vpage mapping that points to a non volume block which would indicate Premature Block Recycle. Also cleans up some of the logging output, like iterating the correct number of vpages when dumping to remove the harmless error log, and no longer logging when bad blocks are found, as that is a normal and safe occurrence. Tested: Against 4 different images with known problems in them, and 1 image that was doctored to induce PPW with the fix.
