crypto/internal/boring: use noescape and nocallback cgo directives The new noescape and nocallback directives can be used instead of the C wrapper functions that are there just to avoid some parameters being escaped to the heap. This CL also helps demonstrate the use of the new directives in real code. I've added some benchmarks to demonstrate that this CL doesn't introduce new heap allocations when using boringcrypto: ``` goos: linux goarch: amd64 pkg: crypto/aes cpu: AMD EPYC 7763 64-Core Processor BenchmarkGCMSeal-32 8378692 143.3 ns/op 111.65 MB/s 0 B/op 0 allocs/op BenchmarkGCMOpen-32 8383038 142.7 ns/op 112.11 MB/s 0 B/op 0 allocs/op ``` Change-Id: Ifd775484eb9a105afc5c3d4e75a6c6655cbadc53 Reviewed-on: https://go-review.googlesource.com/c/go/+/525035 TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Bryan Mills <bcmills@google.com> Run-TryBot: Quim Muntal <quimmuntal@gmail.com> Reviewed-by: Roland Shoemaker <roland@golang.org> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com>
