Add license attribution for target configuration files derived from TinyGo project:
- Document source from https://github.com/tinygo-org/tinygo/tree/release/targets
- Include complete BSD 3-Clause license from TinyGo project
- Clarify licensing terms for target configuration files
- Ensure proper attribution to TinyGo Authors and Go Authors
- Maintain compliance with original license requirements
This ensures proper license compliance when using TinyGo's target configurations
in the llgo project.

Add comprehensive target configuration parsing and inheritance system:
- Create internal/targets package with config structures
- Support JSON configuration loading with inheritance resolution
- Implement multi-level inheritance (e.g., rp2040 → cortex-m0plus → cortex-m)
- Add 206 target configurations from TinyGo for embedded platforms
- Support core fields: name, llvm-target, cpu, features, build-tags, goos, goarch, cflags, ldflags
- Provide high-level resolver interface for target lookup
- Include comprehensive unit tests with 100% target parsing coverage
This foundation enables future -target parameter support for cross-compilation
to diverse embedded platforms beyond current GOOS/GOARCH limitations.
