Implements UTF-8 encoding and decoding for external units with OPEN(ENCODING='UTF-8'). This encoding applies to default CHARACTER values that are not 7-bit ASCII as well as to the wide CHARACTER kinds 2 and 4. Basic testing is in place via direct calls to the runtime I/O APIs, but serious checkout awaits lowering support of the wide CHARACTER kinds. Differential Revision: https://reviews.llvm.org/D122038
