CMake: Add `qt_add_ui` API

This commit introduces a new `qt_add_ui` CMake API to be used instead
of AUTOUIC, due to several hard-to-fix bugs it has.

* Resolves the issue where Ninja required two passes to correctly build
`.ui` files.
* Avoids build folder leakage, in contrast to `AUTOUIC`
* Prevents unnecessary recompilation of unchanged source files when a
`.ui` file is modified with Ninja.
* Since `qt_add_ui` does not scan source files, it provides a faster
build than `AUTOUIC`.

These changes aim to streamline the build process and improve
efficiency when working with `.ui` files.

This addresses the following issues:
