Richard Smith 6fe8e0b5aa Provide generic impls for Core.Int and Core.UInt operations. (#4693) 
Instead of providing operations only for `i32`, provide them for all
`iN` and `uN` types.

For now, this excludes the `*Assign`, `Inc` and `Dec` interfaces,
because the implementations for those are defined as Carbon functions
rather than builtins, and we can't yet lower definitions for specific
functions, so converting those to be generic breaks the build for our
examples.
