Log GlobalStatistics when exporting logs from settings

[Susko3]

Depends on:

• Don't clear Logger.NewEntry handlers when flushing osu-framework#6191
• Framework bump

Has there been a scenario where this change becomes helpful for it? I was weirded out that this PR is here with seemingly no prior discussion anywhere.

I just accidentally stumbled onto GlobalStatistics.OutputToLog() and thought it would be useful information to have in logs.
Also, global statistic data is already available in sentry reports.

To me, this is useful for seeing which input events are happening at a glance, without having to ask follow-up questions, eg. in #26875 (comment). If I were to see a bunch of dropped events there, it would help narrow down the problem.

don't see why not, more logging is rarely bad
