Ensure Fluent messages are in alphabetical order

[clubby789]

Fixes #111847

This adds a tidy check to ensure Fluent messages are in alphabetical order, as well as sorting all existing messages. I think the error could be worded better, would appreciate suggestions.

Script used to sort files

import sys
import re

fn = sys.argv[1]
with open(fn, 'r') as f:
    data = f.read().split("\n")

chunks = []
cur = ""
for line in data:
    if re.match(r"^([a-zA-Z0-9_]+)\s*=\s*", line):
        chunks.append(cur)
        cur = ""
    cur += line + "\n"
chunks.append(cur)
chunks.sort()

with open(fn, 'w') as f:
    f.write(''.join(chunks).strip("\n\n") + "\n")

Looks fine... cc @rust-lang/wg-diagnostics in case anyone else cares, but I generally agree that, since ftl files otherwise have literally no structure except for generally being chronologically ordered, they probably should be just alphabetical.

Should we stick your fmt script into x fmt, too? Then most people will never even hit that check.

tidy already has a --bless mode, so if you RIIR that script it would be easy to put into tidy

Given that it seems like @jyn514 is happy and nobody else has spoken up, r=jyn,me when CI is green.
