Brad King 578d95f87d find_*: Disable the PACKAGE_ROOT search path group for CMake 3.9
Disable the feature added by commit v3.9.0-rc1~71^2~2 (find_*: Add a new
PackageRoot search path group, 2017-05-03) and remove documentation
added by commit v3.9.0-rc1~71^2 (find_*: Add docs for PackageRoot search
path group, 2017-05-03).  Unfortunately the name `<pkg>_ROOT` may
already be set by projects for their own incompatible purposes.  Disable
the behavior change for now to fix the regression for CMake 3.9.  We can
restore it later with a policy.

In order to keep the implementation and tests working, add an
undocumented variable we can use in the tests to enable the behavior
before the policy is introduced.

Fixes: #17144
