Custom model extension

[achauhan-scc]

This pull request introduces the initial implementation of the azure.ai.models extension for the Azure Developer CLI (azd). It adds the core extension configuration, build and test scripts for multiple platforms, Go module dependencies, documentation, and utility code for managing dependencies like AzCopy. The changes lay the foundation for building, testing, and distributing the extension, as well as providing users with clear installation and usage instructions.

Key changes:

Extension Configuration and Documentation

• Added the main extension manifest extension.yaml with metadata, capabilities, and usage examples for managing custom models in Azure AI Foundry.
• Added a comprehensive installation and usage guide in docs/installation-guide.md, including step-by-step instructions and screenshots for installing, initializing, and using the extension.

Build and Test Infrastructure

• Introduced cross-platform build scripts: build.sh (Bash) and build.ps1 (PowerShell), supporting multi-OS/architecture builds, version stamping, and output directory management. [1] [2]
• Added a CI-specific PowerShell build script ci-build.ps1 with support for code coverage, build modes, and advanced Go build flags.
• Added a PowerShell test script ci-test.ps1 that uses gotestsum if available for improved test output, or falls back to go test.

Go Module and Dependencies

• Created the initial go.mod with all required direct and indirect dependencies for Azure SDK, CLI integration, and supporting libraries.

Supporting Utilities

• Implemented internal/azcopy/installer.go, a utility for downloading and installing the AzCopy binary in a cross-platform manner, handling archive extraction and installation paths.
• Added a cspell.yaml file with custom dictionary entries to improve spell checking for domain-specific terms.
