Can we use validateVectorCommon?
The comment in validateVectorCommon points back to #109. So I feel like figuring that out should be part of resolving the issue.

How do you think validateVectorCommon should be modified to support StringView? My idea is
if (vector instanceof BaseVariableWidthViewVector) {
int typeBufferCount = TypeLayout.getTypeBufferCount(arrowType);
validateOrThrow(
fieldVector.getFieldBuffers().size() >= typeBufferCount,
"Expected at least %s buffers in vector of type %s, got %s.",
typeBufferCount,
vector.getField().getType().toString(),
fieldVector.getFieldBuffers().size());
}

Roughly yes but I would prefer adding a TypeLayout.isVariableBuffer instead of hardcoding a type check
