Improve the List View for TalkBack Users

[VoidCrater]

Is your feature request related to a problem? Please describe.
While navigating the file list with TalkBack, users have to swipe thrice to get from one file or folder to another. For every file, TalkBack users hear the file name, "Select button", and the context menu for that file. This makes navigating the file list a bit slower and harder. Also, the context menu button has a wrong label, "Properties".

Describe the solution you'd like
Group the filename with the controls select and context menu (https://developer.android.com/guide/topics/ui/accessibility/principles#content-groups) and add the select and context menu buttons to accessibility actions (https://developer.android.com/guide/topics/ui/accessibility/principles#accessibility-actions) this will streamline navigation for TalkBack Users.
Rename the "Properties" (context menu) button to "Show file actions" (https://developer.android.com/guide/topics/ui/accessibility/principles#label-elements).

Describe alternatives you've considered

@VoidCrater do you think grouping is the ideal strategy in this situation? I didn't try this in practice, but it seems to me this would cause TalkBack to read the unfocusable buttons along the item name. It makes more sense to me to mark these simply as unimportant for accessibility, so TB can skip them during navigation, and expose the functionality through actions as you suggest.

This does not look like a complicated change, if I can get the project to compile, I can play with it and open a PR if I get to something sensible.
