TSDB: move TimeSeriesModeIT to yaml tests (#80933)

I move TimeSeriesModeIT to yaml tests.
I move the below lists to 15_timestamp_mapping.yml:
```
testTimestampMillis -> date
testTimestampNanos -> date_nanos
testAddsTimestamp -> automatically add with date
testBadTimestamp  -> reject @timestamp with wrong type
testDisabledTimeStampMapper -> reject timestamp meta field with wrong type
```

And add some tests in 15_timestamp_mapping.yml:
```
testBadTimeStampMapper  -> reject bad timestamp meta field
testWithoutTimestamp -> write without timestamp
testAddTimeStampMeta -> add timestamp meta
testEnabledTimeStampMapper -> enable timestamp meta field
```

AND move the below lists to 10_settings.yml:
```
testEnableTimestampRange ->  set start_time and end_time
```

And add some tests in 10_settings.yml:
```
testBadStartTime\testBadEndTime ->  set bad start_time and end_time
```
