Update PolymodAbstractScriptClass.hx to have "findVar" in resloveField function

[7oltan]

i wanted to add this to help with my code of making safe scriptSet and safe scriptGet (soft coded) which is basically:
get variable if it doesnt exist return default value
but i cant do that because its not possible to check for a varaible so i added this change

thank you!!

Passing a VarDecl outside the hScript class is un-intuitive and risks breaking stuff.

Maybe instead a hasVar function which returns a boolean if findVar is not null would make more sense here?

Both work, tho I used "findFunction" and it works but idk, the hscript stuff it scares me
