JsAllowValueClassesInExternals language feature had UNSTABLE_FEATURE kind and was enabled by default for JS IR backend. As a result, klibs compiled with recent compiler versions were marked with the pre-release flag. Now, if we enabled reading the flag from klibs, the JS IR compiler would reject all these klibs by default. To fix that, this commit changes the flag value from 0x1 to 0x2, so that all previously compiled klibs are treated as not having the pre-release flag.
