Angular compiler: 100% material-angular match rate (625/625)

Key fixes:
- Fix variable optimization for Statement ops in two-way bindings
  - Added transform_expressions_in_output_statement/expression helpers
  - Properly inline ALWAYS_INLINE alias variables into TwoWayBindingSetExpr
  - Resolves $index handling in @for loops with two-way bindings

- Make HTML parser lenient for unclosed elements (Angular compatibility)
  - Remove error reporting for unclosed elements at EOF
  - Parser still recovers correctly by creating AST nodes
  - Matches Angular TypeScript compiler's lenient behavior
