[TypeSpec] Pin all emitter packages in all language repos

[mikeharder]

For repeatable builds, I think we should be pinning all emitter packages in the language repos using a package-lock.json file. Changes required:

• Pin all top-level packages we care about in eng/emitter-package.json
• Ensure the name property is set in emitter-package.json, so it will be copied to the lockfile and remains stable for all developers.
• Generate and commit a lockfile at eng/emitter-package-lock.json
• Update eng/common/scripts/TypeSpec-Project-Generate.ps1 to copy the lockfile and install using npm ci rather than npm install --no-lock-file.

  • azure-sdk-tools/eng/common/scripts/TypeSpec-Project-Generate.ps1
