Consolidate OpenQASM project loading and include handling

[idavis]

Replaces #2444

• Unified project loading: Consolidated OpenQASM project loading across all components (compiler, language service, Python pip, WASM) to use a single load_openqasm_project method instead of multiple inconsistent approaches
• Improved error handling: Enhanced include file error propagation by properly associating errors with their source spans and include statements in the parent file
• Better error reporting: Include file errors now display with proper source location information, showing the problematic include statement in context instead of generic "Not Found" messages
• API simplification:
  • Removed custom ImportResolver from Python interop in favor of unified project loading
  • Replaced multiple compile_to_qsharp_ast_with_config calls with parse_and_compile_to_qsharp_ast_with_config. With parsing, compilation, and project loading being separated, trying to clear up intent and purpose.
  • Added parse_sources utility function for handling multiple source files
• Enhanced debugging support: Added test coverage for setting breakpoints in multi-file OpenQASM programs with included files
• Code structure improvements:
  • Added Debug and Clone derives to semantic analysis types for better tooling support
  • Consolidated error handling logic into reusable helper functions
  • Improved span tracking for IO errors through the compilation pipeline

The changes ensure consistent OpenQASM project handling across VS Code extension, Python package, WASM builds, and language service while providing better error messages and debugging capabilities for multi-file projects.

Posting a round of comments. Still need to review language service and pip folders
