This starts the process of removing all dependencies from wazero, by isolating all assertions we use into a single file. This allows us to port those assertions as we have time, and when twitchy is gone, the project literally has no dependencies except go! Signed-off-by: Adrian Cole <adrian@tetrate.io>
