all: replace collide mode by `async` call property
Replace the currently existing straightforward approach to race triggering
(that was almost entirely implemented inside syz-executor) with a more
flexible one.
The `async` call property instructs syz-executor not to block until the
call has completed execution and proceed immediately to the next call.
The decision on what calls to mark with `async` is made by syz-fuzzer.
Ultimately this should let us implement more intelligent race provoking
strategies as well as make more fine-grained reproducers.
