On linux-musl-release-x64 builds, the return value from a native function returning false is sometimes incorrectly interpreted as true because of the mismatch between the number of bytes expected for bool on native and managed sides.

Repro:
The host defines a native function bundle_probe with type

bool STDMETHODCALLTYPE bundle_probe(const char16_t* path, int64_t* offset, int64_t* size)

If this function is called from managed code using the following delegate:

 [UnmanagedFunctionPointer(CallingConvention.StdCall)]	        
 public delegate bool BundleProbeDelegate([MarshalAs(UnmanagedType.LPWStr)] string path, IntPtr size, IntPtr offset);

The invocations where bundle_probe return false, are interpreted as true. Gor example:

Probe(bundleProbeDelegate, "", isExpected: false);

Once this issue is fixed, this test asset should be updated to use the bool return type in the PInvoke delegate.
