configurable default radial menu

Is your feature request related to a problem? Please describe.
When using controlify, we need to configure the radial menu for each controller we use. Sometimes, this configuration is missed for some controller detection problem (I suspect that the SO start to identify the same controller with some different id somehow).

Describe the solution you'd like
It'd be nice to have a way to define the default radial options, so they can be determined once for every controller

Describe alternatives you've considered
I manually clean up the json and copy and paste the radial config between controllers

Additional context
This is especially true when we run the game using some split-screen mod. For example, I play with my wife using the same game profile but different users, so we ended up sharing some configs and we use two controllers. It's nice to have a centralized configuration, but sometimes this configs ended up getting radial actions missed and we have to edit it again

Start by tracing how the existing per-controller radial configuration is stored in JSON and how controller detection selects it. Define the default radial options and verify that they apply across controllers while preserving any controller-specific configuration.
