[EH] Change catch_all's opcode (#3574)
We decided to change `catch_all`'s opcode from 0x05, which is the same
as `else`, to 0x19, to avoid some complicated handling in the tools.
See: https://github.com/WebAssembly/exception-handling/issues/147
lso this contains the original cpp file used to generate
dwarf_with_exceptions.wasm; instructions to generate the wasm from that
cpp file are in the comments.
