[X86][TableGen] Remove unnecessary use of formatted_raw_ostream. NFC (#…

…89343)

This code used to use the PadToColumn feature of formatted_raw_ostream,
but no longer does. formatted_raw_ostream is slower than regular
raw_ostream because it has to keep track of the number of character
since the last new line character.
