Show loading state for Commit Composer when diffs take a long time to load

[justinrobots]

Description

When there are many working directory changes, the Commit Composer can take longer to open and show the diffs, but it gives no indication that it is loading. In one case with ~2000 lines and 18 files, it took ~7s to open the view and ~20s to render the diffs.

The Commit Composer should at least indicate when it is taking a long time to load the view and render diffs.

Ideally, the performance of opening the view and rendering diffs should be improved to render diffs as quickly as possible.
