Make AtsJsonCodeWriter a shared internal helper

[Eric Erhardt (eerhardt)]

Description

AtsJsonCodeWriter was only used by the CLI and polyglot code generation projects, so exposing it from Aspire.TypeSystem added public API that consumers do not need. This moves the implementation to src\Shared\Json as an internal helper and link-compiles it into each project that uses it: CLI plus Go, Java, Python, Rust, and TypeScript codegen.

Validation:

• restore.cmd
• dotnet.cmd build for Aspire.TypeSystem, all affected code generation projects, and Aspire.Cli with /p:SkipNativeBuild=true

Fixes # (issue)

Pull request overview

This PR removes an unnecessary public surface area exposure by relocating AtsJsonCodeWriter out of Aspire.TypeSystem and into src/Shared/Json, then link-compiling it into the CLI and polyglot code generation projects that consume it.

Changes:

• Moved AtsJsonCodeWriter into Aspire.Shared.Json and made it internal-only.
• Updated CLI and code generators (Go/Java/Python/Rust/TypeScript) to reference the new shared helper namespace.
• Added shared-source <Compile Include="...AtsJsonCodeWriter.cs" Link="..."> entries to the affected projects.
