This prevents a number of issues where devices are enumerated but not actually able to be opened, like https://github.com/libsdl-org/SDL/issues/5781.
We currently leave the devices open, allowing us to more easily do controller feature detection, protocol negotiation, detect dropped Bluetooth connections, etc. with the expectation that the application is likely to open the controllers shortly.
Unfortunately the only way to detect this is to actually try opening a device, so we wait until the application tries, and then stop enumerating afterwards.

Refactor the previous sandbox check in a standalone function that also
includes Snap support.

The Java code needs the native functions to be implemented, even if
they're not surfaced via the C API, therefore, a stub version of
functions were made only to the purpose of "fill the gaps" when
SDL_HIDAPI_DISABLED set to 1.
