RFR: 8276144: Update boot JDK to 17.0.1

[Kevin Rushforth]

Now that JavaFX has updated to gradle 7.3 -- see [JDK-8276142](https://bugs.openjdk.java.net/browse/JDK-8276142) / PR #671 -- we can update the boot JDK used to build JavaFX to JDK 17.0.1.

I have run a smoke test on all three platforms.

I will run a full set of tests in parallel with the review.
