[homematic] Remove double press events and improve long press events for button trigger (#11186)

Browse Source 
HM devices provide not only 'long press' events, but also 'long
press continued' (sent in configured long press interval) and 'long
press released' events. So far, those events were swallowed in the
button datapoint handler.
Improve the situation by forwarding those events to the button trigger
channel, making them usable in e.g. rules that react on button long
presses.

A double press timeout of 2 seconds is too long and disturbs single
press processing. Additionally, for double press processing to be
useful, the first press would need to be swallowed until double press
timeout elapses, which is not what happened here: the first PRESS was
sent out as SINGLE_PRESS event, making it impossible to meaningfully
distinguish the 'single press' and 'double press' events within rules.

If needed, double press handling can be implemented equally well within
a rule.

@ -343,16 +343,17 @@ A virtual datapoint (String) to simulate a key press, available on all channels
Available values:
- `SHORT_PRESS`: triggered on a short key press
- `LONG_PRESS`: triggered on a key press longer than `LONG_PRESS_TIME` (variable configuration per key, default is 0.4 s)
- `DOUBLE_PRESS`: triggered on a short key press but only if the latest `SHORT_PRESS` or `DOUBLE_PRESS` event is not older than 2.0 s (not related to `DBL_PRESS_TIME` configuration, which is more like a key lock because if it is other than `0.0` single presses are not notified anymore)
- `SHORT_PRESSED`: triggered on a short key press
- `LONG_PRESSED`: triggered on a key press longer than `LONG_PRESS_TIME` (variable configuration per key, default is 0.4 s)
- `LONG_REPEATED`: triggered on long key press repetition, that is, in `LONG_PRESS_TIME` intervals as long as key is held
- `LONG_RELEASED`: triggered when a key is released after being long pressed
**Example:** to capture a short key press on the 19 button remote control in a rule
```javascript
rule "example trigger rule"
when
Channel 'homematic:HM-RC-19-B:ccu:KEQ0012345:1#BUTTON' triggered SHORT_PRESS
Channel 'homematic:HM-RC-19-B:ccu:KEQ0012345:1#BUTTON' triggered SHORT_PRESSED
then
