HDFS-17084. Utilize StringTable for numerable XAttributes

[symious]

Description of PR

Currently only the name of XAttr will utilize SerialNumber's StringTable to store values, for values they are stored as "byte[]".

If the XAttr values are numerable, StringTable could be used for efficiency.

This ticket is to let users create numerable attributes.

JIRA ticket: https://issues.apache.org/jira/browse/HDFS-17084

How was this patch tested?

unit test.

For code changes:

• Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
