Make the module dependency on java.logging optional

Browse Source 
Currently, FlatLaf has the following module dependencies:

$ jdeps --list-deps --multi-release 9 flatlaf-1.0.jar
   java.base
   java.desktop
   java.logging

This commit makes the java.logging dependency optional and hides logging behind a facade that falls back to printing to stderr if the java.logging module is not available.

To test, create a reduced JRE with a command like

jdk-15/bin/jlink.exe --module-path jdk-15/jmods --add-modules java.desktop --add-modules java.instrument --output jre-15-desktop-only

(adding java.instrument, so the FlatLafDemo main class can be started from IntelliJ IDEA)
