Decide on how to return variable-length arrays in the UMemory hierarchy

Description

I made an API proposal for ICU 67 to add a length field to LocalArray so that we can start using it as the go-to construction for returning variable-length arrays across the ICU4C library boundary:

https://sourceforge.net/p/icu/mailman/message/36944083/

However, this was not accepted into ICU 67 because additional discussion was required, such as whether we should create a new class for this, continue using C-style output arrays with a capacity, etc.
