Build failures on 32-bit archs: int overflows

- [x] The issue is present in the latest release: 0.11.4
- [x] I have searched the [issues](https://github.com/ent/ent/issues) of this repository and believe that this is not a duplicate.

## Current Behavior 😯

`ent` doesn't build on 32-bit architectures (e.g. `armel`, `armhf`, and `i386` exhibit the issue, as seen with `autopkgtest` runs on https://ci.debian.net/), due to a few overflows/type issues:

```

```

## Expected Behavior 🤔

It should build.

## Steps to Reproduce 🕹

Build ent in a 32-bit environment. This is easily achieved by setting up an i386 chroot on an amd64 machine.

On Debian/Ubuntu systems, this can be done by throwing the current source package in unstable at cowbuilder, which automates setting up a build chroot, installing build dependencies in it, and cleaning up after a build (successful or not).

Steps:

1. `dget https://deb.debian.org/debian/pool/main/g/golang-entgo-ent/golang-entgo-ent_0.11.3-3.dsc`
2. `sudo cowbuilder --create --distribution unstable --architecture i386 --basepath /var/cache/pbuilder/unstable-i386-base.cow`
3. `sudo cowbuilder --build golang-entgo-ent_0.11.3-3.dsc --basepath /var/cache/pbuilder/unstable-i386-base.cow`

## Your Environment 🌎

Debian unstable, any 32-bit architecture.

| Tech | Version |
| ----------- | ------- |
| Go | 1.19.3 |
| Ent | 0.11.4 |

With the attached patch, the build succeeds, but then runtime tests fail. I'll file a companion ticket for those.
