CMake: Enable overriding the QT_INSTALL_DOCS environment variable

Browse Source 
The QT_INSTALL_DOCS is configured with incorrect path sometimes,
especially while configuring qtbase with QT_HOST_PATH,
which also lets you build documentation for the essential modules
such as QtCore, QtGui, and so on. If the default QT_INSTALL_DOCS
path is wrong, a way to override the path would enable building
documentation for the essential modules without having to build
parts of qtbase.
