Enable builtin formatting hooks

Enable bpfmt, clang_format, and ktfmt instead of ktlint.

ktfmt is better adapted to Android style than ktlint, see
external/ktfmt/README.md. In particular ktlint does not allow comments
with argument names when calling java functions like:

myFunction(/* arg1= */ 0, /* arg2= */ null)

or like:

myFunction(0 /* arg1 */, null /* arg2 */)

Test: upload
