[Development] Remaining tools in CMAKE_INSTALL_BINDIR

[Ulf Hermann]

Hi,

I would consider qml, qmlscene, qmlpreview, qmlprofiler, and qmltime to 
be equivalent to their Qt 5 versions, and indeed user-facing.

qmltc is not user-facing. It's a compiler and should live in the same 
place as qmlcachegen.

qmljs is a general-purpose JavaScript interpreter. So, it's kind of 
user-facing and equivalent to the Qt5 version. We only build it for 
developer builds, though (AFAIK).

qmlplugindump is the same as in Qt5. It should be a build tool, but it 
is not, due to ... shortcomings. People generally invoke it manually. 
Also, it's deprecated in Qt6.

qmldom is a debugging helper for the QmlDom library. As such it is user 
facing, bit it should only be built for developer builds.

best regards,
Ulf
