Andrew Kelley 3ee9d06cbd packed structs support comptime bitcasting ...

* `type_size_store` is no longer a thing. loading and storing a pointer
   to a value may dereference up to `@sizeOf(T)` bytes, even for
   integers such as `u24`.
 * fix `types_have_same_zig_comptime_repr` to not think that the
   same `ZigTypeId` means the `ConstExprValue` neccesarily has the
   same representation.
 * implement `buf_write_value_bytes` and `buf_read_value_bytes` for
   `ContainerLayoutPacked`
