Brad King 314613d1af Add infrastructure for generators to select a build tool instance

Add cache entry `CMAKE_GENERATOR_INSTANCE` to hold the instance location
persistently across re-runs of CMake in a given build tree.

For now we reject the option by default if explicitly set.  It will be
implemented on a per-generator basis.  Pass the setting into try_compile
project generation.  Add a RunCMake.GeneratorInstance test to cover
basic use cases for the option.  Verify that `CMAKE_GENERATOR_INSTANCE`
is empty by default, and that it is rejected when the generator does not
support a user setting.

Issue: #17268

 generator-instance
 ------------------
 * A :variable:`CMAKE_GENERATOR_INSTANCE` variable was introduced
   to hold the selected instance of the generator's corresponding
   native tools if multiple are available.  Currently no generators
   actually use this, but the infrastructure is in place.
