Subject: [PATCH v2 0/3] uapi: Use UAPI definitions of INT_MAX and INT_MIN

Using <limits.h> to gain access to INT_MAX and INT_MIN introduces a
dependency on a libc, which UAPI headers should not do.

Introduce and use equivalent UAPI constants.

Changes in v2:
- Use uapi/linux/typelimits.h over uapi/linux/limits.h
- Drop RFC status
- Link to v1: https://lore.kernel.org/r/20260105-uapi-limits-v1-0-023bc7a13037@linutronix.de
