trait_sel: skip elaboration of sizedness supertrait
As a performance optimization, skip elaborating the supertraits of `Sized`, and if a `MetaSized` obligation is being checked, then look for a `Sized` predicate in the parameter environment. This makes the `ParamEnv` smaller which should improve compiler performance as it avoids all the iteration over the larger `ParamEnv`.
