std: fix compile errors in std.crypto.ecc (#23797)
Implemented `neg()` method for `AffineCoordinates` struct of p256,
p384 and secp256k1 curves.

Resolves: #20505 (partially)

std.crypto.pcurves fixes (#19245)
Fixes compilation errors in functions that are syntaxic sugar
to operate on serialized scalars.

Also make it explicit that square roots in fields whose size is
not congruent to 3 modulo 4 are not an error, they are just
not implemented yet.

Reported by @vitalonodo - Thanks!

d890e81761 mem: fix ub in writeInt
Use inline to vastly simplify the exposed API.  This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.

This reverts commit 0c99ba1eab63865592bb084feb271cd4e4b0357e, reversing
changes made to 5f92b070bf284f1493b1b5d433dd3adde2f46727.

This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.

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

3f1c51ca90 std: remove names from incorrectly named tests
Tests that only reference decls for the purpose of analyzing more tests
should be unnamed, otherwise trying to filter for just a referenced test
can become impossible depending on the names.

std.crypto.ecc: add support for the secp256k1 curve (#11880)
std.crypto.ecc: add support for the secp256k1 curve

Usage of the secp256k1 elliptic curve recently grew exponentially,
since this is the curve used by Bitcoin and other popular blockchains
such as Ethereum.

With this, Zig has support for all the widely deployed elliptic curves
today.
