Paul E. Murphy b61b08db44 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.

Sebastiaan van Stijn ec07f4e35b 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.

Make all our package sources use Go 1.17 gofmt format

Not strictly necessary but will avoid spurious changes
as files are edited.

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.
