Add ParseStmt, ParseExpr and FormatBeautify convenience API

- ParseStmt(sql) parses exactly one statement, erroring on zero or
  multiple statements, so callers no longer need to go through
  NewParser(...).ParseStmts() and validate the slice length.
- ParseExpr(sql) parses an expression fragment (column expression,
  function call, ...) and requires the whole input to be consumed.
- FormatBeautify(expr) renders multi-line indented SQL, the one-call
  counterpart of Format; previously beautified output required wiring
  NewFormatter().WithBeautify().WriteExpr() by hand. The CLI -beautify
  path now uses it.
