Relevant issue: https://github.com/llvm/llvm-project/issues/52705
When the `DisableFormat` option of `clang-format` is set to `true` and a JSON file is formatted, the ephemeral variable binding that is added to the top-level object is not removed from the formatted file. For example, this JSON:
```
{
"key": "value"
}
```
Is reformatted to:
```
x = {
"key": "value"
}
```
Which is not valid JSON syntax. This fix avoids the addition of this binding when `DisableFormat` is set to `true`, ensuring that it cannot be left behind when formatting is disabled.

I find as I develop I'm moving between many different languages C++,C#,JavaScript all the time. As I move between the file types I like to keep `clang-format` as my formatting tool of choice. (hence why I initially added C# support in {D58404}) I know those other languages have their own tools but I have to learn them all, and I have to work out how to configure them, and they may or may not have integration into my IDE or my source code integration.
I am increasingly finding that I'm editing additional JSON files as part of my daily work and my editor and git commit hooks are just not setup to go and run [[ https://stedolan.github.io/jq/ | jq ]], So I tend to go to [[ https://jsonformatter.curiousconcept.com/ | JSON Formatter ]] and copy and paste back and forth. To get nicely formatted JSON. This is a painful process and I'd like a new one that causes me much less friction.
This has come up from time to time:

I would like to stop having to do that and have formatting JSON as a first class clang-format support `Language` (even if it has minimal style settings at present).
This revision adds support for formatting JSON using the inbuilt JSON serialization library of LLVM, With limited control at present only over the indentation level
This adds an additional Language into the .clang-format file to separate the settings from your other supported languages.
