"<scalar> <filter-op> <vector>" takes the sample value from the wrong side

[juliusv]

Describe the bug
In native PromQL, binary filter operators between a scalar and a vector (e.g. 1 < foo) always return the sample value from the vector side of the operation, no matter which side of the operator it is on. VictoriaMetrics always returns the sample value from the left-hand side, even if it is the scalar value.
