Qol(settings): energy saving, simplified UI, better perf

[Mathias-Boulay]

Why does this PR exist ?

This PR aims to make the user experience slightly better:

• It brings a new set of default settings to take into account more (and less) powerful devices.
• It changes a few UI elements to allow the user to focus on the action he wants the most

Notable changes

Changes in behavior

• Resolution, ASR, vsync and sustained performance is tweaked depending on whether a device is considered "powerful"
• The profile selector will now display a simplified profile name if no name is provided. No name is present by default for new profiles
• A new JVM argument is now under control of the launcher. It allows to properly state the amount of cores present on the device, increasing performance slightly.

Refactors

• seekbar increments (among other resources) have been centralised into a resource file and turned into XML settings for their respective views
• some strings have been de-duplicated

Fixes

• The gamepad is now able of the resolution changing on the fly
• (Android <= Q) The notch size was not computed properly in game
