Use is-terminal instead of atty.

Following up on #3696, use the new is-terminal crate to test for a tty
rather than having platform-specific logic in Wasmtime. The is-terminal
crate has a platform-independent API which takes a handle.

This also updates the tree to cap-std 0.24 etc., to avoid depending on
multiple versions of io-lifetimes at once, as enforced by the cargo deny
check.
