Doc: Add missing links to methods to QSet documentation page

Some internal links to `QSet` methods were missing from the
documentation. In particular, all methods that were written with one
attribute.

It seems that QDoc might automatically recognize method/function
links only if they have zero parameters, such that the identifier is
followed by `()` directly.

To avoid this problem while keeping the current parameter-containing
form of the text; each function of the form `functioname(\a
parametername)` was changed to `\l {functionname()} {functioname(\a
parametername)}.

Furthermore, one of those text instances was modified to use `\a` for
the parameter name, instead of the previously used `\e`, to enhance
consistency.

An instance of `operator<<()` was not recognized as a link.
To resolve this it was marked with the `\l` command.

Fixes: QTBUG-95389
