general scripting improvements (the sequel)

[inky03]

implements all proposed hscript fixes in #15621, and has other additional changes:

• (INTERNAL) some of the hscript class code has been overhauled to be more efficient; should still be entirely compatible with versions prior!
  • also added a function to the class run(?functionName, ?functionArguments), similar to executeFunction previously but also allows the main body to be executed if no function name is provided
• FATAL hscript errors and warnings are now logged when luaDebugMode is enabled too, with their own colors
  
  the trace function has also been added to print a message with the line number (highlighted with the cyan color)
• FATAL errors in lua scripts are now only printed in the game's debug console, rather than showing an alert (in windows)
  
  to differentiate them from the rest of the errors and very much like the new fatal hscript errors, they're highlighted in dark red
• Paths.font has been fixed? changed an incorrect variable when getting the font path, so setTextFont in lua API should work correctly now fixed in another pr (which has been merged)
• the reflection functions (like get/setProperty[FromClass]) now allow instance argument parsing inside arrays; this means you can, for instance, set camera filters without needing to use hscript at all
  code example:

  makeLuaSprite('shd')
  setSpriteShader('shd', 'adjustColor')
  createInstance('filter', 'openfl.filters.ShaderFilter', {instanceArg('shd.shader')})
  setProperty('camGame.filters', {instanceArg('filter')}, false, true) -- this was previously not possible!
  setShaderFloat('shd', 'hue', -15)

• callMethod, callMethodFromClass and createInstance now allow you to not pass the arguments array at all; no more {''} (ex. callMethod('openPauseMenu', {''}) -> callMethod('openPauseMenu'))
• if HSCRIPT_ALLOWED is disabled, trying to use hscript related API functions in lua should now actually just show a warning (this was accounted for already, but did not work because the hscript class wasn't even created if the flag wasn't defined)
