Require the Send trait for TargetIsa

Browse Source 
The `TargetIsa` trait already requires that the implementor is `Sync` to
be shared across threads, and this commit adds in an additional
restriction of `Send` to ensure that the type can be sent-by-value
across threads as well.

This is part of an effort to make various data structures in `wasmtime`
sendable/shareable across threads.
