Custom configuration general hotkey customizability

[Heck-R]

1. Problem Description In the Custom configuration, general customConfiguration hotkeys are not provided with the same possibilities as the site-specific customTaskControlCenter shortcuts, namely the arguments: h5Player, taskConf, data.

2. URL where the above issue occurs The described issue is more of a missing general feature, it's not site-specific

3. The browser and browser version information you are using The described issue is more of a missing general feature, it's not browser-specific

4. Other additional information Example implementation: https://github.com/xxxily/h5player/pull/540

This would allow for doing stuff like the following in custom configs:

{
...
    {
      desc: 'Custom action',
      key: 'arrowdown',
      command: (h5Player, taskConf, data) => {...}
    },
...
}
