```
compiler: represent bitpacks as their backing integer

Now that https://github.com/ziglang/zig/issues/24657 has been
implemented, the compiler can simplify its internal representation of
comptime-known `packed struct` and `packed union` values. Instead of
storing them field-wise, we can simply store their backing integer
value. This simplifies many operations and improves efficiency in some
cases.
