Prior to this change, the static error test updater would spawn a new analyzer CLI for each updated test file. This was incredibly slow, like 5-10 seconds for each file. This change instead uses the analyzer as a library. It creates a single analysis context collection for all of the files to be updated and then gets the errors from that. On my machine, it's about 100x faster. It's fast enough to routinely update *all* of the test expectations in a batch. (Or, at least, it will be if we can make a similar change for CFE.)
