feat(bluetooth): UI context aware keybindings

[Euphoriyy]

Ideally, you should be able to bind multiple actions per key binding so that each button can perform multiple functions depending on scenario, e.g. you can go to the next page in the reader and filemanager with one key.

Follow-up to #178.

Maybe it's a different feature request, but additionally, being able to assign multiple keypresses to the same function would be nice. Use case: an 8bitdo Micro can be easily held two different ways, and someone might like to be able to change pages with both buttons AND the direction pad.

@scmaltese that's different, do you mind opening a new issue. Isn't this already possible? I can't see why you can't register the same action to multiple buttons 🤔

If this is not the case, please open a new issue with some reproduction steps and logs 🙏🏾

@Euphoriyy could you give: https://github.com/OGKevin/kobo.koplugin/actions/runs/21112497781?pr=182 a try please.

Sorry for the late response. I thank you for your work! I just tried it with both reader and file browser page turning. It seems to work perfectly! I don't know if it was because of user error or my past configuration, but I also experienced a weird issue in the beginning where the file browser key bindings wouldn't work and the reader key bindings were triggered twice. Perhaps this can be figured out after further testing. But after resetting my key bindings it all seems to work nicely.

On second thought, it seems that if you enable Bluetooth from within the filemanager, then the actions in FileManager mode don't work immediately until you go to the reader (whose actions do work) and back (and vice versa for reader mode). It seems there's an issue with initializing key bindings in each mode on enabling Bluetooth. This doesn't occur if you toggle Bluetooth with a gesture though, so maybe it has something to do with enabling Bluetooth from the menu?

@Euphoriyy are you able to reproduce the issue with debug logs enabled and share your logs 🙏🏾
