[dawn][wire] Fixes crash caused by calling Unmap on an incomplete Buffer. - In the client Buffer, move the handles into the Buffer members eagerly instead of as a part of the serialization function. Otherwise, if the client was disconnected, resulting in the serialization functions not running to completion, the Buffer is left in a bad state when we are created with mappedAtCreation. - Adds tests that I confirmed are failing with either crashes or leaked memory before the fix to ensure that we don't regress.
