Subject: [PATCH] MINOR: [Java] Make StructVector.reallocValidityBuffer
 protected Changes the access modifier of reallocValidityBuffer from
 package-private to protected.

This allows subclasses to reallocate the validity buffer independently of the struct elements. Previously,
expanding the validity buffer required a full vector reallocation, which could cause an OversizedAllocationException
if the child data vectors were already near their capacity.
