chacha20: extend ppc64le support to ppc64
This requires fixing an incorrect save of the counter. It is a word
value. It happens to work on LE because length is limited to u32.
Refactor the constant table to load correctly independent of byte
ordering.
Add byte order swapping where output needs converted to LE
ordering for storage.

chacha20: drop Go 1.10 compatibility for arm64
Other packages already dropped compatibility with go < 1.12, so it should be safe to remove it for this package as well.

all: go fmt ./...
Make all our package sources use Go 1.17 gofmt format
(adding //go:build lines).
Not strictly necessary but will avoid spurious changes
as files are edited.
Part of //go:build change (#41184).
See https://golang.org/design/draft-gobuild

all: build tags: appengine,!gccgo => purego,gc
appengine is obsolete and superseded by purego, and gc is a more
precise tag for files that use gc-syntax assembly.

chacha20,poly1305,chacha20poly1305: set consistent build tags
appengine was only necessary for the legacy system based on Go 1.9, drop
that. Add purego tags instead. Remove redundant architecture tags.

chacha20: expose internal/chacha20 package
const KeySize = 32
const NonceSize = 12
func HChaCha20(key, nonce []byte) ([]byte, error)
type Cipher struct {}
func NewUnauthenticatedCipher(key, nonce []byte) (*Cipher, error)
func (s *Cipher) XORKeyStream(dst, src []byte)
Small performance hit in chacha20poly1305, probably due to the loss
of the Advance API, which we might consider adding later. No new
allocations, thanks to the mid-stack inliner.
