Fix Textarea TV Input Options (#16747)

### What does it do?
Makes array checking strict in the method used for evaluating boolean
option types.

### Why is it needed?
Autogrow and Resizable option settings were not displaying/saving
correctly.

I have no idea how/why this issue did not crop up when these options
were added originally, not too long ago :-/

### How to test
Create a textarea TV and change these input options to verify they
persist as expected.

### Related issue(s)/PR(s)
Resolves #16746
