Limit time range when querying labels and label values

[secfree]

Currently parca scans the whole table when querying "labels" and "values" of a label. Even "start" and "end" have already been defined and reserved in the definition, they are not transmitted. This PR add time range limitation to these queries and avoid the whole table scanning.

Below is the "Explain" of the "QueryBuilder"

TableScan [concurrent] - PredicateFilter ((name == parca_agent AND (sample_type == samples AND (sample_unit == count AND (period_type == cpu AND (period_unit == nanoseconds AND duration != 0)))))) - Projection (labels) - Synchronizer

TableScan [concurrent] - PredicateFilter ((name == parca_agent AND (sample_type == samples AND (sample_unit == count AND (period_type == cpu AND (period_unit == nanoseconds AND duration != 0)))))) - Projection (labels.comm) - Distinction (labels.comm) - Synchronizer - Distinction (labels.comm)

After applying this PR, they have "(timestamp > xxx AND timestamp < yyy)"

TableScan [concurrent] - PredicateFilter ((name == parca_agent AND (sample_type == samples AND (sample_unit == count AND (period_type == cpu AND (period_unit == nanoseconds AND (duration != 0 AND (timestamp > 1749980021601 AND timestamp < 1749983621601)))))))) - Projection (labels) - Synchronizer
