ARROW-12146: [C++][Gandiva] Implement CONVERT_FROM(expression, replacement char) function

Implement CONVERT_FROM(expression, ‘UTF8’, replacement char)

Converts the byte data in expression to UTF-8. Expression can be a literal string or a field name. Will replace any invalid UTF-8 characters with the replacement character.

Obs.: Actually we will only support a single byte replacement char

Closes #9844 from jpedroantunes/feature/convert-replace-utf8 and squashes the following commits:
