Ajax: Don't treat array data as binary
PR gh-5197 started treating all non-string non-plain-object `data` values as binary. However, `jQuery.ajax` also supports arrays as values of `data`. This change makes regular arrays no longer be considered binary data. Surprisingly, we had no tests for array `data` values; otherwise, we'd detect the issue earlier. This change also adds a few such missing tests. Closes gh-5203 Ref gh-5197
