[roll] Roll fuchsia [fidl] Remove debug assertion that boolean value is 0 or 1

There currently is a debug assertion in the bool WireCodingTraits that
ensures that bool values are 0 or 1 in the encode direction. However,
the reinterpret_cast in this check uses UB.

This check should not be needed unless there is memory corruption
because the bool value is already guaranteed to be 0 or 1. Given this,
this CL removes the unnecessary check.
