[Feature Request/Proposal] Rename "Cache" directory setting to "Temp"

so this is getting nitpicky. however those of you that know me, know im ocd and i like my polish/consistency lol.

this was actually brought to light just now due to setting retroarch up on my shield android tv units.

it automatically creates its "cache" directory as a folder called "temp" and if you attempt to change it, it just re-creates it/returns it anyways.

I assumed it was similar to the reasoning why you cant change the "cores" folder on android - but its not as it is in the emulated storage dir whereas the cores folder is not for permissions reasons.

anyhow, the windows platform creates no such folder, and up until now I had created a folder called "cache" and pointed retroarch at it.

as noted i couldnt do this on the shield and it got me thinking. All of the different retroarch directories point to folders with the exact name of what they are and what the setting is called. This makes finding things very easy.

The glaring exception is "cache" which then got me thinking, its not really a cache at all. It truly is just a temp dir.

The resolution could go two ways. changing the default for retroarch's cache dir on android to storage/0/emulated/Retroarch/cache (may have butchered the path but you get the idea) instead of storage/0/emulated/Retroarch/temp or simply changing the name of the setting from "Cache" to "Temp" or "Temp Folder" which i think makes more sense as its not really a cache at all.

is this a small thing in the grand scheme? yes, willing to admit that. Hopefully its trivial enough to be a 5 minute fix.

Trace the Cache directory setting and compare how its defaults or displayed name are handled on Android and Windows. Resolve whether the setting should be renamed to Temp or the Android directory should be changed, then verify the chosen behavior is consistent with the other directory settings.
