* Add a compilation section to disable address maps
This commit adds a new `Config::generate_address_map` compilation
setting which is used to disable emission of the `.wasmtime.addrmap`
section of compiled artifacts. This section is currently around the size
of the entire `.text` section itself unfortunately and for size reasons
may wish to be omitted. Functionality-wise all that is lost is knowing
the precise wasm module offset address of a faulting instruction or in a
backtrace of instructions. This also means that if the module has DWARF
debugging information available with it Wasmtime isn't able to produce a
filename and line number in the backtrace.
This option remains enabled by default. This option may not be needed in
the future with #3547 perhaps, but in the meantime it seems reasonable
enough to support a configuration mode where the section is entirely
omitted if the smallest module possible is desired.
* Fix some CI issues
* Update tests/all/traps.rs
