Style editor: Add MaxScale and MinScale parameter to style editor rules.

[Inogeo]

Is your feature request related to a problem? Please describe.

When I want to display symbol and label at distinct scale range on the same layer, I have to create a map, with separate layers for symbols and label (with different scale range rules each).

Describe the solution you'd like Instead of setting the scale range here (see screenshot below):

Define the scale range inside a "rule" directly in the style editor.

The SLD properties<MaxScaleDenominator>[MIN_RANGE_VALUE]</MaxScaleDenominator> and <MaxScaleDenominator>[MIN_RANGE_VALUE]</MaxScaleDenominator>

The interface could look like this:

These select lists for max/min scales can be then added to every rules types.

Describe alternatives you've considered None.

Additional context None.
