Deduplicate listings of traps in Wasmtime (#5299)

This commit replaces `wasmtime_environ::TrapCode` with `wasmtime::Trap`.
This is possible with past refactorings which slimmed down the `Trap`
definition in the `wasmtime` crate to a simple `enum`. This means that
there's one less place that all the various trap opcodes need to be
listed in Wasmtime.
