yyforyongyu 390f3c8253 channeldb: expand PaymentStatus to explicitly represent payment status ...

This commit introduces more granular statuses to better determine a
payment's current state. Based on whether there are inflight HTLCs, the
state of each of the HTLCs, and whether the payment is failed, a total
of 5 states are derived, which can give a finer control over what action
to take based on a given state.

Also, `fetchPayment` now uses `decidePaymentStatus`. After applying the
new function, the returned payment status would be different,

```
| inflight | settled | failed | reason |       previous  ->   now          |
|:--------:|:-------:|:------:|:------:|:---------------------------------:|
|   true   |   true  |  true  |   yes  |    StatusInFlight(unchanged)      |
|   true   |   true  |  true  |   no   |    StatusInFlight(unchanged)      |
|   true   |   true  |  false |   yes  |    StatusInFlight(unchanged)      |
|   true   |   true  |  false |   no   |    StatusInFlight(unchanged)      |
|   true   |   false |  true  |   yes  |    StatusInFlight(unchanged)      |
|   true   |   false |  true  |   no   |    StatusInFlight(unchanged)      |
|   true   |   false |  false |   yes  |    StatusInFlight(unchanged)      |
|   true   |   false |  false |   no   |    StatusInFlight(unchanged)      |
|   false  |   true  |  true  |   yes  |    StatusSucceeded(unchanged)     |
|   false  |   true  |  true  |   no   |    StatusSucceeded(unchanged)     |
|   false  |   true  |  false |   yes  |    StatusSucceeded(unchanged)     |
|   false  |   true  |  false |   no   |    StatusSucceeded(unchanged)     |
|   false  |   false |  true  |   yes  |     StatusFailed(unchanged)       |
|   false  |   false |  true  |   no   |     StatusInFlight(unchanged)     |
|   false  |   false |  false |   yes  |     StatusFailed(unchanged)       |
|   false  |   false |  false |   no   |  StatusInFlight -> StatusInitiated|
