Fuse operations in `equal_rows_arr`

[Dandandan]

Is your feature request related to a problem or challenge?

equal_rows_arr compares pairs of 2 arrays with indices for equality but shows up in profiles.

Currently this is done in the following way

• take the values for the indices for the first pair
• comparing the arrays using eq or not_distinct
• doing the same for the next pairs and anding the results
• Filtering the indices based on the resulting boolean array

Describe the solution you'd like

We could optimize this in some ways:

• writing a kernel that doesn't use take (i.e. copy the array) but compares arrays based on the indices.
• writing results to a single booleanbuffer rather than creating a new one every time
• removing indices from the list (e.g. using Vec::retain) not matching rather than creating a boolean array for a filter
