Instead of treating `Core.Int` as the toolchain's builtin `IntType`, model it as a class that adapts the builtin type. This aligns us better with the intended language model, gives an associated library for `impl`s involving `Core.Int` to live within, and opens the door adding member functions to `Core.Int` if we decide that is desirable. Remarkably it also seems to make the formatted SemIR a little smaller, because a call to a generic class generates less IR than a call to a function.
