Upgrade to the latest versions of gimli, addr2line, object (#2901)

* Upgrade to the latest versions of gimli, addr2line, object

And adapt to API changes. New gimli supports wasm dwarf, resulting in
some simplifications in the debug crate.

* upgrade gimli usage in linux-specific profiling too

* Add "continue" statement after interpreting a wasm local dwarf opcode
