std.crypto: remove inline from most functions
...
To quote the language reference,
It is generally better to let the compiler decide when to inline a
function, except for these scenarios:
* To change how many stack frames are in the call stack, for debugging
purposes.
* To force comptime-ness of the arguments to propagate to the return
value of the function, as in the above example.
* Real world performance measurements demand it. Don't guess!
Note that inline actually restricts what the compiler is allowed to do.
This can harm binary size, compilation speed, and even runtime
performance.

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

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.
