Make Luke launching code faster [LUCENE-10588]

[asfimport]

Starting Luke can take multiple seconds since it renders all GUI components when launching; It could be possible to make it faster (within sub-second) by lazily rendering panels to avoid loading too many classes when starting.

This typically becomes an issue on CI job, but a quicker launch would be also good for humans. https://github.com/apache/lucene/pull/917
