narrow allowSmartActionArgs disabling

currently, allowSmartActionArgs is disabled for the whole hotspot and jdk test suites and enabled just in few places. this makes it a bit harder for people to use smart action arguments in these test suites as they have to not to forget to enable them. and given in all the other test suites, smart action arguments are enabled, it can be confusing and frustrating.

this RFE is to enable allowSmartActionArgs in both hotspot and jdk test suites and just disable it in a handful number of test directories whose use cases aren't fully supported by jtreg yet.
