test: Add test for struct schema evolution matching by index

[rui-mo]

The default behavior of schema evolution on struct field is matching by index.
This PR adds corresponding tests for the below cases.

Parquet column schema	User-specified output schema	Result
row({"a", "c"})	row({"a", "b", "c"})	row(a:a_val, b:c_cal, c:null)
row({"a", "c"})	row({"b"})	Should not be supported, no deletion of subfields
row({"a", "c"})	row({"b", "d"})	row(b:a_val, c:d_val)
row({"a", "c"})	row({})	Should not be supported
