Instead of creating the tool wrapper shell script only
during a Qt build in QtBuild.cmake,
ensure it is created any time _qt_internal_wrap_tool_command is
called, regardless if we're building Qt or a user project.
As a transitional period not to break compatibility, we also need
to create the script in QtBuild.cmake, until all usages of
QT_TOOL_COMMAND_WRAPPER_PATH are replaced with function calls.
Currently such usages are present in qtdeclarative.
When considering which bin dirs to add to the script's PATH
environment variable assignment, in addition to the build
internals relative bin dir, also add QT_BUILD_DIR,
QT_ADDITIONAL_PACKAGES_PREFIX_PATH and QT6_INSTALL_PREFIX.
QT_BUILD_DIR is important so we always pick up the just-built
but not installed libraries in a prefix build when running just-built
tools.
QT_ADDITIONAL_PACKAGES_PREFIX_PATH is important when building examples
as ExternalProjects in prefix builds, to ensure that the
not-yet-installed tools and libraries are picked up from the repo
build dir, which is passed via QT_ADDITIONAL_PACKAGES_PREFIX_PATH
to the external projects.
QT6_INSTALL_PREFIX is there in case if the build internals relative
dir is located in a different places than the Qt6 package.
