Description

[Dan Minor [:dminor]]

Once we support fetching wasm modules, we can look at compiling them. We may end up splitting this bug into smaller pieces as well.

Attachment: Bug 1997621 - Add web-platform test for direct import of wasm modules in worklets; r=allstarschh!

The existing worklet test triggers a syntax error because we don't yet
support source phase imports. This adds a direct import so we can test
worklet loading of wasm modules. This test is expected to fail because
we don't support compiling wasm modules yet, but is sufficient to test
the module loading code.

WASM modules are raw bytes, we should add a different DataType so
we don't attempt to decode them as UTF-8 or UTF-16.
