d1c2d865 - Forward declare TextEncodingConverter in TextEncoding.h, move config.h into TextEncoding.cpp (#207382)

Forward declare TextEncodingConverter in TextEncoding.h, move config.h into TextEncoding.cpp (#207382) This patch forward declares TextEncodingConverter in clang/include/clang/Lex/TextEncoding.h, and moves config.h into llvm/lib/Support/TextEncoding.cpp instead of the header.
