Andreas Kling 18c40a1328 LibJS/Rust: Fix has_parameter_expressions and TDZ checks for arguments ...

Fix two bugs in the Rust bytecode codegen:

1. has_parameter_expressions incorrectly treated any destructuring
   parameter as a "parameter expression", when it should only do so
   for patterns that contain expressions (defaults or computed keys).
   This caused an unnecessary CreateLexicalEnvironment for simple
   destructuring like `function f({a, b}) {}`. The same bug existed
   in both codegen.rs and lib.rs (SFD metadata computation).

2. emit_set_variable used is_local_lexically_declared(index) for
   argument locals, but that function indexes into the local_variables
   array using the argument's index, checking the wrong variable.
   This caused spurious ThrowIfTDZ instructions when assigning to
   function arguments that happened to share an index with an
   uninitialized let/const variable.
