Replace the generated C++ legacy codec implementations with a small Rust wrapper around encoding_rs. This keeps the existing LibTextCodec API while moving label lookup, legacy decode/encode, validation, and streaming decoder state to Rust. The generated index data and generator are no longer needed. It also fixes several TextDecoder EOF cases due to a more correct implementation. encoding_rs finalizes decoders according to the Encoding Standard, so incomplete UTF-8/Big5 tails and malformed UTF-16 surrogate tails produce the required single replacement at end-of-queue instead of being dropped, buffered, or double-counted by our old hand-written decoders.
