QtSupport: Add support to register Qt versions via qtpaths

qmake is a "build tool", and it is also a "query tool" when called with
parameter "-query". Qt Creator, so far, assumes that building and
querying with a Qt installation are done with one and the same tool:
qmake. This change adds the ability to register a Qt version vie either
qmake or qtpaths and still build with qmake, if that is installed (which
is not anymore mandatory from Qt 6 on).

1) Distinguish between Qt query tool and qmake build tool:
Add QtVersion::queryToolFilePath() to the existing
QtVersion::qmakeFilePath(), and use queryToolFilePath in most "query"
related code, and qmakeFilePath when building with qmake (e.g. in
QmakeProjectManager).
Also, a couple of functions and variables were renamed from *qmake* to
*queryTool* in order to express that the affected code is about
querying/managing Qt versions rather than about building with qmake.

2) Support manual Qt Version adding by qtpaths via file dialog
This change adds qtpaths to the "Add" Qt Version file picker filter.
After selection, "qtpaths -query" is executed for testing purposes. If
that fails, (e.g. because it is an older Qt version), qmake is instead
chosen, silently.
