Summary: Now that gentest has been used to cover all flexbox properties as well as some internal behavior I thought it was time to remove the old CSSLayoutTest.cpp. This removes a huge amount of previously regex transpiled code in favor of the new test suite which does more fine grained assertions and uses the public api. Given that RTL support was added to gentest now I feel confident that the new test suite covers all and more cases than the old one.
