lib/storage: validate timestamps in the block only if they use encoding, which needs validation
This reduces CPU usage when there is no sense in validating timestamps.

This is a follow-up for 5fa9525498

lib/storage: verify that timestamps in block are in the range specified by blockHeader.{Min,Max}Timestamp when upacking the block
This should reduce chances of unnoticed on-disk data corruption.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2998
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3011

This change modifies the format for data exported via /api/v1/export/native -
now this data contains MaxTimestamp and PrecisionBits fields from blockHeader.

This is OK, since the native export format is undocumented.

lib/storage: deduplicate samples more thoroughly
Previously some duplicate samples may be left on disk for time series with high churn rate.
This may result in higher disk space usage.

lib/storage: explicitly pass dedupInterval to DeduplicateSamples() and deduplicateSamplesDuringMerge()
This improves the code readability and debuggability, since the output of these functions
stops depending on global state.

95688cbfc5 all: add native format for data export and import
The data can be exported via [/api/v1/export/native](https://victoriametrics.github.io/#how-to-export-data-in-native-format) handler
and imported via [/api/v1/import/native](https://victoriametrics.github.io/#how-to-import-data-in-native-format) handler.

24ca30bf66 lib/storage: correctly use maxBlockSize in various checks
Previously `maxBlockSize` has been multiplied by 8 in certain checks. This is unnecessary.

0b488f1e37 lib/storage: do not change timestamps to constant rate if values are constant or have constant delta
This breaks the original timestamps, which results in issues like
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/120 and
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/141 .
