The CLI currently uses `File.OpenWrite(path)` (added in #2677) to create an output stream for the resulting swagger document. This does not delete the existing contents, but instead starts writing from position 0, causing issues if the output is smaller than the previous file content.

Changed to `File.Create(path)` to make sure any previous content is discarded.

The previous implementation caused the concurrent builds for various frameworks to compete in writing to the output `swagger.json` file, causing exceptions during builds (since it happened in csproj).

In my local development I often failed to rebuild the full solution because some projects failed to build for this reason. It has also happened in CI (#2886).

Note that the NSwag source code generator in `NswagClientExample` still outputs everything in one spot for all frameworks, but I haven't noticed failures from that. Maybe it's just less likely to write concurrently. I left it as is.

Un-skip the `Overwrites_Existing_File` test.

Replace any `<br>` tags with a new line instead.

* Add schema filter test for when example tag is not present

* Add datetime to schema filter example tag positive test

* Fix missing example property on record xmldoc param tag causing unexpected empty example string in generated schema

Speed up local development iterations by only running `npm install` when the `node_modules` directory does not already exist.

Apply code refactoring suggestions from Visual Studio.

Extend custom `JsonSerializerContext` to cover objects that might be added to the additional JSON property.
Resolves #2884,

Disable parallel build to avoid file-write conflicts.
Relates to #2893.

- Remove `IHostedService` implementations so the CLI doesn't run hosted services (and then hang/fail).
- Refactor CLI tests to reduce duplication.
- Use newer C# syntax as suggested by Visual Studio.
