Add overflow check when converting large strings to lists columns

[davidwendt]

Description

Fixes a couple places where strings columns are converted to lists column as binary -- chars are represented as INT8.
Since lists columns only support size_type offsets type, this change will throw an error if the size of the chars exceeds max size_type values.

Perhaps it would be better to check the strings offsets type instead since the type is the real issue regardless of the chars size?
I welcome any opinions here.

My suggestion is to check the char_size. if a user can't convert large strings, the user may choose to batch it using slices < 2 GB. then offsets type will still remain same but it is possible to perform this operation.
Also, could we move the size check before the column contents are copied?
