[PATCH 1/3] scripts: add spelling_sanitizer.sh script

[Zhen Lei]

The file scripts/spelling.txt recorded a large number of
"mistake||correction" pairs. These entries are currently maintained in
order, but the results are not strict. In addition, when someone wants to
add some new pairs, he either sort them manually or write a script, which
is clearly a waste of labor. So add this script. It removes the duplicates
first, then sort by correctly spelled words. Sorting based on misspelled
words is not chose because it is uncontrollable.
