Move new zha_event command parameters into a params key to ensure backwards compatibility

Proposed change

A recent ZHA dependency upgrade (#68921) changed zigpy's response type to a list-compatible object that had attached type schemas. While the responses superficially worked, they caused problems with some types of comparisons. This change brings back the old behavior of keeping ZHA event data in a list object while migrating named ZHA event parameters into a new key:

{
    "event_type": "zha_event",
    "data": {
        "device_ieee": "90:fd:9f:ff:fe:fe:d8:a1",
        "unique_id": "90:fd:9f:ff:fe:fe:d8:a1:1:0x0008",
        "device_id": "51e3449d17f2fd47abebd16b6721d470",
        "endpoint_id": 1,
        "cluster_id": 8,
        "command": "step_with_on_off",
        "args": [
            0,
            43,
            5
        ],
+       "params": {
+           "step_mode": 0,
+           "step_size": 43,
+           "transition_time": 5
+       }
    },
    "origin": "LOCAL",
    "time_fired": "2022-04-07T17:55:49.966102+00:00",
    "context": {
        "id": "a92cda22a798ea82c6d0b7c7e4500dd9",
        "parent_id": null,
        "user_id": null
    }
}

If you feel this new params key should be split off into a separate PR, let me know.

This change still doesn't make every comparison backwards comaptible: my ikea switch was sending [0, 43, 5] before, but is now sending [<StepMode.Up: 0>, 43, 5]

Had the same issue here

@bernikr StepMode.Up == 0 so any comparisons will still work. What is being broken for you?

[bernikr]

If used in a template the args will translate to a string with the content '[<StepMode.Up: 0>, 43, 5]'. All further comparisons with this then break.
