Add a QHttpHeaders convenience method for unique header name setting
The function replaces one of the found entries with the new value,
and removes any other entries. If no entries are found, a new entry
will be appended. The replacement search is done for performance
reasons; it's cheaper to replace an existing value.
All in all the function is a more convenient and performant
alternative for this sequence (which proved to be common while
porting QtNetwork internals to QHttpHeaders):
header.removeAll(<headername>);
header.append(<headername>, <value>);
[ChangeLog][QtNetwork][QHttpHeaders] Added replaceOrAppend()
convenience method, which either replaces previous entries with
a single entry, or appends a new one if no entries existed
Fixes: QTBUG-122175
