Damien Neil d0b074956d proto: rearrange test messages
Move the test inputs for the wire marshaler and unmarshaler out of
decode_test.go and into a new file. Consolidate some tests for invalid
messages (UTF-8 validation failures, field numbers out of range) into
a single list of invalid messages. Break out the no-enforce-utf8 test
into a separate file, since it is both complicated and conditional on
legacy support.
