Add a `__wasilibc_deinit_environ` function which clears the current environment variable state to the state where next time the environment variable functions are called, they'll reinitialize the environment. And add a `__wasilibc_maybe_reinitialize_environ_eagerly` function to reinitialize the environment variable state if `environ` or `_environ` are needed. These functions are needed by wizer to be able to suspend and resume a program and have it read new environment variables from the host environment; see bytecodealliance/wizer#8 for background.
