LibWeb: Allow importing ChaCha20-Poly1305 JWK without alg

Browse Source 
The WebCrypto specification does not require the "alg" member
to be present when importing a symmetric JWK, as long as the
key material itself is valid.

Add tests covering JWK import without an "alg" field.

This fixes the following WPT:
WebCryptoAPI/import_export/ChaCha20-Poly1305_importKey
