Dmitri Shuralyov 8779cbd1c9 all: update go directive to 1.18 
Done with:

go get go@1.18
go mod tidy
go fix ./...

Using go1.21.3.

Also update avo to v0.5.0 in the curve25519/internal/field/_asm module.
It's newer and produces no diff in the generated code.

For golang/go#60268.

Filippo Valsorda c07d793c2f curve25519/internal/field: fix generator module reference to x/crypto 
The generator submodule needs a module dependency on golang.org/x/crypto
to find the type information it needs.

This removes the Comment call from CL 319469 because it does not seem to
generate the intended output. See golang/go#46155.

Fixes golang/go#46133

Filippo Valsorda 3497b51f5e curve25519: replace field implementation with filippo.io/edwards25519 
This imports the crypto/ed25519/internal/edwards25519/field package from
CL 276272, and uses it in x/crypto/curve25519.

The ScalarMult code was ported 1:1 from curve25519_generic.go.

                                old code lines     new code lines

Go                              896                463
Assembly (manually written)     1772 (1772)        362 (34)

43% performance loss on amd64, 33% loss on 386, and 45% gain on arm64.
Feels worth it to remove 1700 lines of manually written assembly.
