[RFC]: Add C implementation for `@stdlib/stats/base/dists/chisquare/quantile`

### Description

This RFC proposes adding a C implementation, including a Node.js native addon, C benchmarks, and C examples, for the [`@stdlib/stats/base/dists/chisquare/quantile`](https://github.com/stdlib-js/stdlib/tree/develop/lib/node_modules/@stdlib/stats/base/dists/chisquare/quantile) package.

When adding support, the following tasks should be completed:

1. A C source implementation should be added to a `src` folder within the package's directory.
2. A native add-on interface should be added in order to call the C implementation from JavaScript.
3. A JavaScript file should be added to the `lib` folder to allow benchmarking and unit testing the native implementation from JavaScript.
4. A new test file should be created which includes unit tests testing against expected behavior.
5. C benchmarks should be added which measure performance for the C source implementation.
6. A file containing C examples should be added to demonstrate example usage.
7. JavaScript benchmarks should be added which measure performance for the native add-on.
8. Build and configuration files should be added to allow compiling and running the C source implementation using project `make` commands (as documented below).
9. The README should be updated to include documentation for the added C API.

To provide a concrete example of what a PR adding the desired method should contain, see https://github.com/stdlib-js/stdlib/pull/3354, which is a PR adding a C implementation for the CDF of an arcsine distribution. This should provide an idea of what is expected.

#### Prerequisites

1. Review JavaScript implementation in `lib/main.js` and its required modules to identify all `stdlib` functions used.
2. Verify C implementations exist for each required function.

### Questions

No.

### Other

Once the implementation is ready including C examples and benchmarks, we should be able to run the following `make` commands.

#### Build native add-on

```bash
NODE_ADDONS_PATTERN="@stdlib/stats/base/dists/chisquare/quantile" make install-node-addons
```

#### Run C examples

```bash
make examples-c-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/chisquare/quantile/examples/c/example.c"
```

#### Run C benchmarks

```bash
make benchmark-c-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/chisquare/quantile/benchmark/c/benchmark.c"
```

#### Run JavaScript benchmarks

```bash
make benchmark-javascript-files FILES="$(pwd)/lib/node_modules/@stdlib/stats/base/dists/chisquare/quantile/benchmark/benchmark.native.js"
```

#### Run all tests

```bash
make TESTS_FILTER=".*/@stdlib/stats/base/dists/chisquare/quantile/.*" test
```

Review lib/main.js and its required modules first, then compare the expected package structure with PR #3354. Verify C implementations exist for each dependency before adding the C source, native addon, examples, benchmarks, tests, build files, and README updates. Run the listed make commands and the package-filtered test command to confirm the implementation is complete.
