Add SDK build validation workflow for real spec files

This commit introduces a GitHub Actions workflow that generates and validates SDKs using the real Appwrite spec files instead of the generic test spec.

- Add sdk-build-validation.yml workflow that generates SDKs from real spec files
- Add generate-sdk.php script to generate individual SDKs by platform
- SDKs are properly categorized by platform (client, server, console)
- CLI SDK uses console platform as intended
- Each SDK is built with its respective toolchain to validate successful compilation
- Workflow runs on pull requests with matrix strategy for parallel execution

Supported SDKs:
- Client: web, flutter, apple, android, react-native
- Server: node, php, python, ruby, dart, go, swift, dotnet, kotlin
- Console: cli
