[Strings] Adopt new instruction binary encoding (#5714)
See WebAssembly/stringref#46.
This format is already adopted by V8: https://chromium-review.googlesource.com/c/v8/v8/+/3892695.
The text format is left unchanged (see #5607 for a discussion on the subject).
I have also added support for string.encode_lossy_utf8 and
string.encode_lossy_utf8 array (by allowing the replace policy for
Binaryen's string.encode_wtf8 instruction).
