Pick up *Tools components also from host Qt
Let find_package(Qt6 COMPONENTS LinguistTools) for a cross-compiled
Qt fall back to search LinguistTools in the host Qt.
Use the same trick as in QtModuleDependencies.cmake: Prepend both
CMAKE_PREFIX_PATH and CMAKE_FIND_ROOT_PATH with the QT_HOST_PATH
(respective ${QT_HOST_PATH}/lib/cmake).
Furthermore adding ${QT_HOST_PATH}/lib/cmake to PATHS argument
makes sure that find_package will work even with NO_DEFAULT_PATH.
Make sure not to match ShaderTools and Tools packages.
ShaderTools is the cross-compiled package, the host package name is
ShaderToolsTools.
Tools is the cross-compiled module from qttools.
Allow an opt out via a QT_NO_FIND_HOST_TOOLS_PATH_MANIPULATION
variable in case that we accidentally match more packages ending in
Tools that are actually cross-compiled packages.
Pick-to: 6.1 6.2
Fixes: QTBUG-95602
