Added the entry Show Disk Usage on Log panel's contextual menu to show the main disk usage of the emulator.
It reports VFS disk usage (with the exception of useless usb directories) and cache disk usage.
I avoided to automatically display the disk usage, e.g. when refreshing the game list, just because the disk usage calculation can require some time (so it will slow down the emulator). So I opted to provide the functionality on demand.
This PR is propaedeutic to #6008. A separated PR to complete #6008 will follow. It will allow multiple selection of games on game list and a contextual menu to manage the removal of the selected games.

Computing directory size is a heavy task. Especially for network drives. Furthermore users don't typically read the logs unless their games froze or crashed. Logs are developer-oriented.

Edit: NVM, I see that it is done on user request only.

Yes. I saw it can take some time even on a m2 (2 seconds on my hw to scan 180 GB on dev_hdd0 with many files). So I opted for an on demand feature. I avoided to provide a dialog box or a button on main menus or tools bar. It seems to me enough to provide that feature on Log panel only with a minimum effort. It's just a stat displayed

@Megamouse is there still something blocking the merge?
