feat(tazjin/german-string): add constructor method from owned data r/8535

Makes it possible to construct a GermanString from an owned byte vector, without
having to clone the data.

This is done by "disowning" the vector using ManuallyDrop to access its internal
pointer. For transient strings, this memory is then owned (and freed) by the
GermanString instance.

Small strings are copied out of the heap and stored inline as before, to avoid
any dereferencing operations.
