RFR: 8369432: Add Support for JDBC 4.5 MR [v6]

[Lance Andersen]

> This PR adds support for the upcoming JDBC 4.5 MR which provides the following  updates to the JDBC specification:
> 
> - Deprecate SQLPermission for removal
> - Enhance the Blob/Clob/Array/SQLXML/NClob interfaces to extend/support AutoClosable
> - Add the SQL types DECFLOAT, JSON to Types.Java and JDBCType.java
> - Add the quoted identifier methods that **were added previously to the Statement interface in JDK 9** to the Connection interface
>   - It is the exact same verbiage & default methods used when these methods were added to the Statement interface
> - Clarify the Timestamp::hashCode method which incorrectly indicates that nanos are not used when calculating the hash
> 
> Tiers 1-3 have been run
