This commit replaces the 5 fuzzers that previously tested LibTextCodec with a single fuzzer. We now rely on the fuzzer to generate the encoding and separate it from the encoded data with a magic separator. This increases the overall coverage of LibTextCodec and eliminates the possibility of the same error being generated by multiple fuzzers.
