Selector for array fields

[timka-s]

Add the ability to create selectors for arrays (like from function - SPLIT(Tags, ', ')), or fix unnest array filtration)
Show unnest([array_field]) in selector values, but filter any([array_field]) in (%selected values%)

Details:
If we have string field like Tags

We can create selector with Tags

Or with UNNEST(SPLIT([Tags], ', '))

But, if we choice unnest value, we will receive error - "set-returning functions are not allowed in WHERE"
SQL: ... unnest(string_to_array(t4.Tags, ', ')) = 'owner' ...

On the other side, filtration for SPLIT(Tags, ', ') works fine:

SQL: ... 'owner' = ANY(string_to_array(t4.Tags, ', ')) ...
