wasm-scope-info requires SIMD, since it prints the value of the SIMD
value in scope. We skip it using statusfile when SIMD is not supported.

The wasm-scope-info-liftoff.js and wasm-set-breakpoint-liftoff.js tests
were originally testing the Liftoff path (when we still had the Wasm
interpreter), and have received some updates along the way. Nowadays the
interpreter is going and the non-liftoff versions of these tests don't
provide any additional test coverage, but are merely a slightly less
updated version of the liftoff test.

This fixes local names that are the string representation of a valid

Even though both the Liftoff and the interpreter-based test are changed,
only the latter needs to be fixed right now since Liftoff does not use
the names currently. Modifying the test just ensures that we implement
this correctly once we use the name.

2) We need to load spilled values from the stack frame.

Currently the inspector reports Wasm in one of two ways:
- If there is a source map, report one script per Wasm script, with
bytecode but no source.
- If there is no source map, report one script per Wasm function, with
source (Wasm disassembly) but no bytecode.
With this change, behavior with source map is same, but without source
map it will report both ways. This will allow us to change the frontend
to do its own disassembly, allowing us to remove the per-function scripts
in a future change.
