Correctly view non-text files in single file window and Open Quickly (#…

…1820)

* add `updateStatusBarInfo` view modifier

* fix QuickLook previews in single file window

* change `fileURL` type to `NSURL` in `AnyFileView`

* fix QuickLook previews in Open Quickly

Use `dismantleNSView` in `AnyFileView` to prevent crashes when using Open Quickly.
What crashes?
1. When using Open Quickly without the workaround in `AnyFileView`, search for a media file (.png, .gif, .mp4, etc)
2. Press escape to close Open Quickly
3. re-open Open Quickly. The media preview is gone
4. Attempt to navigate upwards or downwards using the arrow buttons
5. A crash occurs (QuickLook is attempting to reuse an already closed preview)

* add assertionFailure in `CodeEditWindowController.openQuickly` for when an editorManager or statusBarViewModel is unavailable

* make `UpdateStatusBarInfo.fileURL` an optional

* remove the need to pass environment objects to `NonTextFileView`

This also prevents Open Quickly previews from updating the status bar

* rename function parameters in `UpdateStatusBarInfo` view modifier

* remove `updateStatusBarInfo` view extension

* remove guard in `CodeEditWindowController.openQuickly`

editorManager and statusBarViewModel environment objects are not used in Open Quickly anymore

* merge #1822 fix into this branch

allow files with a utType that is neither image nor PDF to be previewed (#1822)
