Several of the cmake bat files sets "script_dir_path". The problem
is that those assignments are not local to the script files. E.g
when qt-configure-module.bat gives it a value, and then call
qt-cmake.bat, qt-cmake.bat will assign it a different value. And
this value will overwrite the original value in
qt-configure-module.bat. So when the call returns, that script can
sometimes fail.
This happens (for unknown reasons) if the Qt source code path
contains a link to a different drive, created with mklink /d.
This is typical if Windows is running in a virtual machine, and
the Qt source code is shared with the host on e.g drive Q:.
In that case you might want to a folder on C: be a symlink to Q:, in
order to build Qt.
This patch will make sure we add "setlocal" in all the affected
bat files, so that any changes done to e.g "script_dir_path"
stays local to each file.
Pick-to: 6.5 6.6 6.7
