extractIsolation crash with inout argument

[pbk20191]

Description

It seems like extractIsolation does not support inout arguments.

Since inout is useful for something like TaskGroup, AsyncIteratorProtocol.
extractIsolation should support inout arguments too.

Reproduction

func bug<TaskResult>(
    body: @Sendable (inout Void) async -> sending TaskResult
) {
    let boom = withoutActuallyEscaping(body) {
        extractIsolation($0)
    }
    
}
