Improve the namespace validation in xml to record conversion

[Nuvindu]

Description

When defining a Ballerina record with a namespace prefix, an error occurs during XML conversion if the XML value uses a different prefix for the same namespace URI.

@xmldata:Namespace {prefix: "soap", uri: "http://schemas.xmlsoap.org/soap/envelope/"}
public type ResponseBody record {
    CheckPhoneNumberResponse CheckPhoneNumberResponse?;
};

If the XML value uses the prefix "s" instead of "soap" for the same namespace (http://schemas.xmlsoap.org/soap/envelope/), a namespace mismatch error occurs during the conversion process.

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body>
        <CheckPhoneNumberResponse>
            <!-- Response details -->
        </CheckPhoneNumberResponse>
    </s:Body>
</s:Envelope>

Steps to Reproduce

1. Define a Ballerina record with a namespace prefix ("soap").
2. Attempt to convert an XML value using a different prefix ("s") but the same namespace URI.
3. Observe the namespace mismatch error
