IOS/USB: Emulate Wii Speak using cubeb

Android: Don't dismiss AdvancedMappingDialog when pressing Clear

If you already have a mapping set in the advanced mapping dialog and
want to change it, the easiest way to do it is to press Clear and then
select the new mapping from the list. But pressing Clear causes the
dialog to close, forcing you to open it again, which is inconvenient.
This commit makes it so the Clear button doesn't close the dialog.

This feature allows overriding the frequency of the Vertical Blank Interrupt. For many games, this means that their gameplay speed will change without affecting audio, which would be useful by itself (e.g. grinding in RPGs).

However, there are games that use delta time for their game logic, which allows them to be played at >60 FPS at the same gameplay speed!

Some games aren't dynamic though, and require a patch to adjust their game speed variable.

Old cruft from when the Android code was loading INI files manually.
We don't have any handling for failing to load settings anymore.

This change also updates related comments to reflect how things actually
work nowadays.

Android: Don't call NativeLibrary methods during class init

There's no guarantee that directory initialization has completed by this
point, so we can't safely use NativeLibrary.

I'm making this change because of a crash being reported in Google Play
Console. The exact way it's crashing is mysterious to me, so I'm not
sure if this commit fixes the crash, but I think this commit is
a reasonable change to make even if it doesn't fix the crash. Backtrace

a1691a4 made it so analytics start events can only be generated when
starting the main activity. However, some users launch Dolphin's
emulation activity from a separate frontend application, bypassing
Dolphin's main activity. This change adjusts the logic so that start
events can be generated if any activity is started after 6 hours of
inactivity. This more closely matches the behavior we had before
a1691a4, while still ensuring duplicate start events aren't generated.

I've also fixed the inconsistent indentation in ActivityTracker.kt.
