Replace Plugin.getLog() with static ILog.of(Class)

Switch the six single-call-site static log(IStatus) helpers to use
ILog.of(SomeClass.class) instead of routing through the plugin singleton.
This removes the last logging-only reason these bundles rely on
getDefault()/getPlugin() and works even before the activator has stored
the singleton.

Affected bundles:
- org.eclipse.compare.win32
- org.eclipse.unittest.ui
- org.eclipse.ui.console
- org.eclipse.core.variables
- org.eclipse.ant.core
- org.eclipse.ant.ui

All of these already require org.eclipse.core.runtime >= 3.29, which is
when ILog.of(Class) was introduced, so no MANIFEST changes are needed.
