8319192: Remove javax.swing.plaf.synth.SynthLookAndFeel.load(URL url)

[prrace]

Back in JDK 21 we deprecated-for-removal SynthLookAndFeel.load(URL) and targeted it to be removed under this bug ID in JDK 25 .. which is now here.

No open tests needed to be updated to accommodate this removal
I did find one closed manual test, written to explicitly test this API back when it was added, and I'll need to remove that, but it doesn't affect this PR.

There will be a CSR (and probably a release note too).

Ah. I'd forgotten that. I had updated it back in JDK 21 but it slipped my mind this time round.

I'll remove the relevant text.
Hmm, is that specific text part of the spec needed for the CSR ? I didn't include it in the JDK 21 case, and it seems to be just examples, so I am going to say no.
