[jsscripting] Improve logging on JS error (#16445)

* [jsscripting] Improve script error logging
* [jsscripting] Suppress some warnings
* [jsscripting] Throw ISE instead of RE
* [jsscripting] Minor null annotation improvements

Include fileName or ruleUID or transformation UID in the logger name used by the logged error stack trace.
