Craig Scott 5cb0a730c9 Help: Clarify behavior of search ignore-related variables
Not all the behaviors of CMake variables for ignoring search
locations by find_...() commands were fully documented.
Add the missing effects, clarify the wording and restructure the
way the details are assembled to reduce duplication.

Also improve the cross-referencing to ensure all the related
variables are more discoverable.

|CMAKE_IGNORE_VAR| is populated by CMake as part of its platform
and toolchain setup. Its purpose is to ignore locations containing
incompatible binaries meant for the host rather than the target platform.
The project or end user should not modify this variable, they should use
|CMAKE_IGNORE_NONSYSTEM_VAR| instead.
