And use it in the `cmCMakePresetsGraphReadJSON.cxx` to check
presets schema version in the declarative way.

Many modern code editors have support for JSON Schema. When you specify
the `$schema` property in a JSON file, the editor can provide features
like auto-completion, error checking, etc., which can improve your
efficiency when writing and modifying the `CMakePresets.json` file.
Add `--test-output-truncation` to `ctest`. This option can be used to
customize which part of the test output is being truncated. Currently
supported values are `tail`, `middle` and `head`.
Also add equivalent `CTEST_CUSTOM_TEST_OUTPUT_TRUNCATION` variable.
Fixes: #23206
There are some valid use cases for allowing these files to be outside
the project directory. Relax the restriction, and include a strong
warning in the documentation.
Before this refactoring, presets had a simple flag that marked them
as "user" or "not user", and checking the file graph of two files
was as simple as checking this flag. This only allowed for two files
in the graph. Generalize the code to allow for arbitrarily many files
in the graph.
