Prepare std/crypto/pcurves for ecdsa and other curves (#8670)
Functions generated by Fiat-crypto are not prefixed by their description any more. This matches an upstream change.

We can now use a single type for different curves and implementations.

The field type is now generic, so we can properly handle the base field and scalars without code duplication.

std.crypto: add support for the NIST P-256 curve (#8627)
Uses verified code generated by fiat-crypto for field arithmetic, and complete formulas to avoid side channels.

There's still plenty of room for optimizations, especially with a fixed base. But this gives us a framework to easily add other similar curves.
