[MIR] Complete document parsing and printing

Implement the single LLVM-compatible MIR document path with structured\nembedded-IR references, YAML mappings, constants, and deterministic printing.\n\nKeep pointer LLT widths DataLayout-derived, reject layout-dependent output\nwhen embedded IR is omitted, and record the fixed-baseline compatibility\ncontract and regression coverage.
