std.crypto.pcurves.*: simpler, smaller, faster u64 addition with carry (#19644)
signature/s:

Algorithm        Before     After
---------------+---------+-------
ecdsa-p256        3707       4396
ecdsa-p384        1067       1332
ecdsa-secp256k1   4490       5147

Add ECDSA to the benchmark by the way.

f26dda2117 all: migrate code to new cast builtin syntax
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:

* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change

crypto: add support for the NIST P-384 curve (#11735)
After P-256, here comes P-384, also known as secp384r1.

Like P-256, it is required for TLS, and is the current NIST recommendation for key exchange and signatures, for better or for worse.

Like P-256, all the finite field arithmetic has been computed and verified to be correct by fiat-crypto.
