std.crypto: add AES-SIV and AES-GCM-SIV - #25249

Conversation
The Zig standard library lacked schemes that resist nonce reuse. AES-SIV and AES-GCM-SIV are the standard options for this. AES-GCM-SIV can be very useful when Zig is used to target embedded systems, and AES-SIV is especially useful for key wrapping. Also take it as an opportunity to add a bunch of test vectors to modes.ctr and make sure it works with block ciphers whose size is not 16.

The Zig standard library was missing schemes that are resistant to nonce reuse.
AES-SIV and AES-GCM-SIV are the standard solutions for this.
AES-GCM-SIV is particularly useful when Zig is targeting embedded systems, while AES-SIV is especially valuable for key wrapping.
I also took this as an opportunity to add a set of test vectors to
modes.ctrand to ensure it works with block ciphers whose block size is not 16.
