Turbo Fire overhaul

[sonninnos]

Description

The mission was to remove the need of going to global inputs for binding the turbo button, and thus allow everything under one single menu, and also save turbo options to remaps, since they are under Quick Menu Controls.

Behavior by default does not change, since toggle is enabled by default, and bind is empty by default, therefore old port-specific bind is used.

• Turbo Bind is a dedicated RetroPad button instead of a separate bind
• Added a toggle option with hotkey for freeing up the bind without unbinding
• Allowed "Single Button" mode to use all buttons and follow remapping
• Renamed all config keys to start with input_turbo_* for consistency, so old configs beware
• Defaulted "Duty Cycle" to 0 and made it automatic half period
• Refactored remapping caching for restoring settings on remap unload
• Fixed help label of "Allow D-Pad"
• XMB gets extra fancy icons for bind items
