This commit begins implementing accepted proposal #21209 by making `std.builtin.CallingConvention` a tagged union. The stage1 dance here is a little convoluted. This commit introduces the new type as `NewCallingConvention`, keeping the old `CallingConvention` around. The compiler uses `std.builtin.NewCallingConvention` exclusively, but when fetching the type from `std` when running the compiler (e.g. with `getBuiltinType`), the name `CallingConvention` is used. This allows a prior build of Zig to be used to build this commit. The next commit will update `zig1.wasm`, and then the compiler and standard library can be updated to completely replace `CallingConvention` with `NewCallingConvention`. The second half of #21209 is to remove `@setAlignStack`, which will be implemented in another commit after updating `zig1.wasm`.
