Andreas Kling ac35ef465b LibJS: Emit ThrowIfTDZ before simple assignment to let variables 
The Rust bytecode codegen was missing a TDZ check before assigning to
local let/const variables in simple assignment expressions (a = expr).
The C++ pipeline correctly emits ThrowIfTDZ before the store to ensure
temporal dead zone semantics are enforced.

Add an emit_tdz_check_if_needed helper matching the C++ equivalent,
and call it in the simple assignment path.
