Mirror of ada-url/ada#1322 (same change to the vendored copy in src/ada_idna.cpp).

ensure_tables() used to store a permanent failure when new (std::nothrow) could not allocate the table buffer, so every later IDNA call in the process failed even after memory became available.

An allocation failure now stores the uninitialized state and returns false, so a later call can take the init slot again. A checksum or inflate mismatch still stores the permanent failure. A thread waiting on a peer that abandoned an allocation returns immediately instead of spinning until the timeout.

This is fine but it would probably do nothing in practice. In Node.js, it is likely that an out of memory is just an halt which would be correct.
