Added new setContent() overloads, that:
- take parameter of new ParseOptions enum type for specifying the parse
options that can be used for enabling namepsace processing and, in
future, whitespace-only text nodes, etc.
- use ParseResult for returning the information about error message,
line and coulmn number, instead of three parameters for each.
- use QAnyStringView for a QString input data.
To avoid ambiguities when calling setContent() with one argument,
removed the default argument for errorString from all the overloads.
[ChangeLog][QtXml][QDomDocument] Added new setContent() overloads that
allow specifying different parse options through ParseOptions flags.
These overloads use a new ParseResult struct for returning the
information about an error, and QAnyStringView for passing string input.
[ChangeLog][QtXml][QDomDocument][Potentially Source-Incompatible Changes]
setContent() overloads that take only one argument now return
ParseResult instead of a bool. ParseResult explicitly converts to bool,
so the expressions calling setContent() with one argument will continue
compiling, if they are contextually convertible to bool. If an implicit
convertion is required (e.g. bool b = doc.setConetnt(data)), the result
needs to be explicitly converted to bool first
(e.g. bool b = bool(doc.setConetnt(data)).
