Subject: [PATCH] wasm-decompile: Fix unescaped characters in data output.
 (#2500)

Characters `"` and `\` which have special meaning in data
representations are not escaped by wasm-decompile and are passed to
output as is.
This PR fixes such incorrect behavior.
All tests still pass (although no cases are added).
