Allow non-character codes in utf8 strings

Changed the processing of non-character code handling in the UTF8 codec.
Non-character codes are now accepted in QStrings, QUrls and QJson strings.
Unit tests were adapted accordingly.
For more info about non-character codes,

[ChangeLog][QtCore][QUtf8]
UTF-8 now accepts non-character unicode points; these are not replaced
by the replacement character anymore

[ChangeLog][QtCore][QUrl]
QUrl now fully accepts non-character unicode points; they are encoded as
percent characters; they can also be pretty decoded

[ChangeLog][QtCore][QJson]
The Writer and the Parser now fully accept non-character unicode points.
