QUrl: Improve Punycode overflow handling
Add more overflow checks from the sample code in RFC 3492.
Also check if a code point to be inserted into output is in
the allowable range for Unicode.
Rewrite all overflow checks to use {add,mul}_overflow()
functions.
Do not try to process any inputs that are too long to be
part of a valid domain name label.
This fixes a test in tst_qurlinternal.
Fixes: QTBUG-95689
Pick-to: 6.2
