Description

Currently when we compare range/vector equals, we first compare vector Field by its equals method, in this case, it’s hard to specify whether compare names or metadata.

Implement a TypeEqualsVisitor will make type comparisons more flexible like cpp implementation dose https://github.com/apache/arrow/blob/master/cpp/src/arrow/compare.cc#L712
