WIP add compile PI: 8238080: FXMLLoader: if script engines implement javax.script.Compilable compile scripts

[ronyfla]

This WIP adds a "compile" process instruction ("") to fxml files with the optional PI data "true" (default) and "false". The PI data is turned into a boolean value using "Boolean.parseBoolean(String)".

This makes it possible to inject the compile PI everywhere in a FXML file and turn on and off compilation of scripts if the scripting engine implements the javax.script.Compilable interface.

This version builds upon #129.

============================ test units for: compile PI

tests/system/src/testscriptapp2/java/mymod/myapp2/FXMLScriptDeployment2Compile_Off.java
... no compile PI given, starts out to not compile scripts by default, therefore no script gets compiled; each script code starts with "demo_02_"

tests/system/src/testscriptapp2/resources/mymod/myapp2/demo_02_off.fxml
... no compile PI given, starts out to not compile scripts by default, therefore no script gets compiled

tests/system/src/testscriptapp2/java/mymod/myapp2/FXMLScriptDeployment2Compile_Off_On.java
... alternatively uses compile PI to turn compilation off and on; the script code starts alternatively with "demo_02_" and "RgfPseudoCompiledScript.eval(", depending on the state set with the PI

tests/system/src/testscriptapp2/resources/mymod/myapp2/demo_02_off_on.fxml
... starts out explicitly with "" switching the state after each element containing a script

---

tests/system/src/testscriptapp2/java/mymod/myapp2/FXMLScriptDeployment2Compile_On.java
... uses PI "compile true" such that no script gets compiled; each script code starts with "RgfPseudoCompiledScript.eval("

tests/system/src/testscriptapp2/resources/mymod/myapp2/demo_02_on.fxml
... uses PI "" (this PI defaults to true as if "" was given) to turn on compilation of scripts
