[RFC PATCH v1 4/9] freezer: Set default freeze priority for userspace tasks

[Zihuan Zhang <zhangzihuan@kylinos.cn>]

The freezer framework now supports per-task freeze priorities. To
ensure consistent behavior, this patch assigns a default freeze
priority (FREEZE_PRIORITY_NORMAL) to all newly created userspace tasks.

This helps maintain deterministic freezing order and prepares the
ground for future enhancements based on priority-aware freezing logic.

Kernel threads are not affected by this change, since they are excluded.
