Optimize timer callbacks

It turned out that esp_event was adding extra complexity to the code base and it was completely unnecessary. So it has been removed from the component completely. The actions are now executed directly in the `relay_chn_distpacth_cmd()` and `relay_chn_tilt_dispatch_cmd()` functions.
This change has simplified the component as well as reduced the memory footprint.

Fixes #1084, refs #1083
