Add setclassvariable to yjit (#5127)
Implements setclassvariable in yjit. Note that this version is not
faster than the standard version because we aren't handling the inline
cache in assembly. This is still important to implement because it will
prevent yjit from exiting in methods that call both a cvar setter and
other code that yjit can compile.
