ICU-20158 Pass ByteSink all the way to _uloc_(addLikely|minimize)Subtags().

This eliminates the need for scratch buffers in any code path that ends
with these functions and also eliminates the need for counting bytes,
something that ByteSink will now handle correctly when needed.

Existing calls to uloc_addLikelySubtags() and uloc_minimizeSubtags()
throughout ICU4C implementation code are also updated to instead use
either the Locale or ulocimp_* functions with the new API.

None of this should have any externally visible effect, it's all about
cleaning up implementation internals.
