gh-98925: Lower marshal recursion depth for WASI (GH-98938)



For wasmtime 2.0, the stack depth cost is 6% higher. This causes the default max `marshal` recursion depth to blow the stack.

As the default marshal depth is 2000 and Windows is set to 1000, split the difference and choose 1500 for WASI to be safe.
