Trap if the suspender argument provided to the JSPI import
wrapper is invalid.

For now, the suspender argument is expected to be the active
suspender. In the future, it will also be possible to suspend
to a parent of the current suspender. This will only be possible
once wasm-to-wasm suspending wrappers are supported, or if and
when JSPI suspenders become compatible with their core
stack-switching counterpart (e.g. Fibers in the fiber proposal).
