Update the v8 crate used when fuzzing (#3929)

A recently discovered fuzz bug reported a difference in execution result
between Wasmtime and v8. The module in question had an exported function
which had multiple results, including floats. About a year ago I
reported a bug on v8 about functions with multiple results leading to
incorrect results, and it was fixed many months back but I don't think
that we ever actually pulled in that update. After updating v8 I saw the
test failure go away, so this update is being done to fix the fuzz bug
test failure I saw.
