Prepare NativeLineBreaker.LineBreaks to be public API

This is a ground work of making NativeLineBreaker/MeasuredParagraph
public.

This CL rename NativeLineBreaker.LineBreaks to NativeLineBreaker.Result.
This CL also moving array re-allocation logic from native code to Java in
StaticLayout. Ideally, we can remove array but this CL keeps array since
that introduces additional complexity.

Here is a raw perf test result:
