Updated the data view info when selection is applied

[N-thony]

Fixes #7277
I have added the info concerning the column selection when it is applied to DataView, I also adjusted the size of the info when the application is minimized or maximized.
@africanmathsinitiative/developers @rdstern this is ready for review. Thanks.

I am approving, because it now works. But I wonder whether we should try to do better? Here it is with a select and a filter

This is default and they are incredibly small. I am not good on design, but suggest that
a) When a filter if active we say Rows 1 to 108, i.e. we only have the word "Showing" when there is no filter. Similarly for Selects?
b) We drop the word Active in each case as well. So it is just Filter::, and Selection?

@N-thony and @shadrackkibet what is your view?

[rdstern]

Approving, but also see comment with a suggestion.

[shadrackkibet]

@rdstern I agree.

@N-thony please change.

@rdstern I made the above change, please test.

Code looks good.
@rdstern @N-thony I wonder why you preferred the column label selection going horizontally.
I'd suggest it to be added vertically. Add this can be done only when there is a column selection. This way we won't need to reduce the font size.

[shadrackkibet]

@rdstern if you approve then we can merge.

[rdstern]

@shadrackkibet I am approving, though I quite like @Patowhiz suggestion. If merged as it stands, then perhaps this can be considered later? As you wish.

@N-thony could you open an issue for this? then you can consider it on a separate PR.

@rdstern another option is to put the label at the top where variable's names are.
