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
