Merge #13190: Have gArgs handle printing help
4d4185a Make gArgs aware of the arguments (Andrew Chow) Pull request description: Instead of each binary generating and printing it's own help string, have gArgs know what the args are and generate the help string. This is the first commit of #13112 pulled out. Tree-SHA512: d794c872b834bc56c78d947549f9cf046a8174984ab0c7b4ba06bc51d36dca11a4ed88afafe76bb4f776cdba042e17e30b9c2ed7b195bef7df77a1327823f989
