RFR: 8343004: Adjust JAXP limits [v2]

[Joe Wang]

> Adjust JAXP Limits. Limits are adjusted as specified in the CSR.
> 
> Tests: 
>      Updated the config test with the new settings.
> 
>      Removed obsolete tests Bug6309988.java and Bug4674384_MAX_OCCURS_Test.java, and files used by these tests. These tests verified legacy properties. They came into the JDK from the JAXP and SJSXP standalone libraries. Improvements were made before the integration into the JDK via for example, SJSXP Issue 30. Though the issue tracker is no longer accessible, the tests, e.g. IssueTracker30, are in the JAXP test suite.
