Feature: Show total and remaining files left in transfer

### What feature or improvement do you think would benefit Files?

I want the status center to show the remaining files in addition to the transfer speed when copying files, so that when copying a large number of small files, it is clear how many files are left (this sentence uses machine translation, which may cause language problems)

### Requirements

- The status center shows the number of files remaining

### Files Version

3.0.8.0

### Windows Version

10.0.22631.2715
