RFR: 8337280: Include jdk.jsobject module with JavaFX [v5]

[Kevin Rushforth]

> Add the `jdk.jsobject` module to JavaFX. This module is currently delivered by the JDK, but will be terminally-deprecated in  JDK 24 by [JDK-8311530](https://bugs.openjdk.org/browse/JDK-8311530), which is out for review at openjdk/jdk#20555. We therefore plan to start delivering it with JavaFX in JavaFX 24.
> 
> ### Testing scenarios
> 
> Both JDK and JavaFX for some period of time, so we need to test various scenarios. I built and tested this PR branch with each of the following JDKs:
> 
> 1. JDK 23 or earlier (I used the default boot JDK, which is currently JDK 22.0.2); this JDK includes `jdk.jsobject` as a normal, non-upgradable module
> 2. A locally-built JDK 24 from my [8311530-depr-jsobject](https://github.com/kevinrushforth/jdk/tree/8311530-depr-jsobject) branch, which has the fix for [JDK-8311530](https://bugs.openjdk.org/browse/JDK-8311530); this JDK includes `jdk.jsobject` as a terminally-deprecated, upgradable module
> 3. A locally-built JDK 24 from my [WIP-rm-jsobject](https://github.com/kevinrushforth/jdk/tree/WIP-rm-jsobject) branch, which removes the `jdk.jsobject` module, and is therefore a prototype of what will happen in JDK 26 (or later) when it is removed from the JDK
> 
> I ran a build and test of JavaFX from this PR branch using each of the above JDKs. All tests pass.
> 
> I then took the JavaFX artifacts built by JDK 1 (matching how we will deliver this in JavaFX 24), and ran the following additional tests, all of which match my expectations:
> 
> * java --module-path=.../jfx/build/sdk/lib without any additional flags (required for JDK 1; recommended for JDK 3) <br> RESULT: JDKs 1 and 2 use the `jdk.jsobject` module from the JDK; JDK 3 uses the `jdk.jsobject` module from JavaFX
> * java --module-path=.../jfx/build/sdk/lib --upgrade-module-path=.../jfx/build/sdk/lib (recommended for JDK 2, OK for 3) <br> RESULT: JDK 1 will fail to launch; JDKs 2 and 3 use the `jdk.jsobject` module from JavaFX
> * jlink with .../jfx/build/jmods ahead of $JAVA_HOME/jmods (recommended for JDKs 2 and 3) <br> RESULT: JDK 1 will fail to link; JDKs 2 and 3 use the `jdk.jsobject` module from JavaFX
> * jlink with $JAVA_HOME/jmods ahead of .../jfx/build/jmods (required for JDK 1) <br> RESULT: JDKs 1 and 2 will use the `jdk.jsobject` module from the JDK; JDK 3 uses the `jdk.jsobject` module from JavaFX
> 
> I have not verified the maven artifacts, but they are being generated correctly.
