RFR: 8350689: Turn on timestamp and thread metadata by default for java.security.debug

[Sean Coffey]

Removal of the `+thread` and `+timestamp` options that were used to control the logging behavior of output from the `java.security.debug` system property.


To enhance the security debug logs, the thread and timestamp data should always be present. This brings it to a par with another important security debug system property, the TLS debug property: javax.net.debug. Output from the TLS `javax.net.debug` logs always contains thread and timestamp data.

This patch remove the `+thread` and `+timestamp` support code and print thread and timestamp data by default. This enancement is only proposed for the JDK feature release. Update releases can continue to opt into such data.

Debug output data from use of the `java.security.debug` property will now resemble something like the following:



properties[0x10|main|Security.java:122|2025-05-01 14:59:42.859 UTC]: Initial security property: package.definition=sun.misc.,sun.reflect.
properties[0x10|main|Security.java:122|2025-05-01 14:59:42.859 UTC]: Initial security property: krb5.kdc.bad.policy=tryLast


I've also trimmed back on some of the test case coverage since use of `+thread` and `+timestamp` options is now redundant with this patch.
