chore: add our own GPU GUI for SCALE (#18254)

**Description**
We want to migrate away from using TrueNAS-Only GPU elements where we
can.
On top of this, the "allocate x" language in the way iX-Systems has
designed the GPU selection GUI is *terrible*.

This replaces said GUI with our own.

**⚙️ Type of change**

- [x] ⚙️ Feature/App addition
- [ ] 🪛 Bugfix
- [x] ⚠️ Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] 🔃 Refactor of current code

**🧪 How Has This Been Tested?**
<!--
Please describe the tests that you ran to verify your changes. Provide
instructions so we can reproduce. Please also list any relevant details
for your test configuration
-->

**📃 Notes:**
For the NVIDIA GPU's to work, we likely need a runtime selection trick
added to common.
