[Bug]: HashCode Exception When Nested Records Contain Duplicate Field Names

[Ajai-Suvendran]

Description

While performing data mapping in Ballerina, an issue arises when a record contains two fields, one of which is another nested record. If the nested record has a field with the same name as a field in the outer record, it causes a hashCode exception, as seen in the following stack trace:
at java.base/java.util.Objects.hashCode(Objects.java:103)
at org.wso2.ballerinalang.compiler.bir.model.BirScope.hashCode(BirScope.java:29)
This issue may occur due to duplicate field names in the hierarchy, leading to a conflict during compilation or runtime.
