Update list of developer tools

The list of tools in https://doc.qt.io/qt-5/topics-app-development.html is incomplete, and the selection of mentioned tools also somewhat arbitrary.

Missing are tools like

• balsam
• canbusutil
• dumpcpp
• dumpdoc
• idc
• lconvert
• lprodump
• lrelease-pro
• lupdate-pro
• pixeltool
• [qdbusviewer|https://doc.qt.io/qt-5/qdbusviewer.html
• qdoc
• qml
• qmleasing
• qmlformat
• qmlimportscanner
• qmllint
• qmlmin
• qmlplugindump
• qmlpreview
• qmlprofiler
• qmlscene
• qmltestrunner
• qmltyperegistrar
• qscxmlc
• qtdiag
• qpaths
• qtplugininfo
• qvkgen
• rcc
• repc
• testcon
• tracegen
• uic
• windeployqt
• xmlpatterns
• xmlpatternsvalidator

Now not all of the tools are meant to be used directly by the user, nor are all important.

I suggest that we do two things:

• Try to group tools
• Do generate the list automatically from the (sometimes) existing individual tool documentation

• qmlimportscanner
• qmllint
• qmlmin
