Fix PluginWrapper bug and cleanup Javadoc placeholders (#25984)

* Fix synchronization, PluginWrapper bug, and cleanup Javadoc

- Fix inconsistent synchronization in Fingerprint.java on 'usages' field by synchronizing on 'this'.
- Fix logic bug in PluginWrapper.java where setOptionalDependants passed incorrect field instead of parameter.
- Replace Boolean.getBoolean with SystemProperties.getBoolean in Jenkins.java and JnlpSlaveRestarterInstaller.java for best practices.
- Update placeholder version numbers (@deprecated and @SInCE) in StreamTaskListener, StreamBuildListener, and JNLPLauncher.
