refactor(axtask): replace wait queue boolean wake flags with explicit policy

[Sasuke0723]

Summary

• add ReschedPolicy for wait queue wake operations
• add notify_one_with, notify_many_with, and notify_all_with
• keep existing boolean-based APIs as compatibility wrappers
• migrate internal call sites and examples to the explicit API

Why

• boolean arguments like notify_one(true) are not self-explanatory
• this keeps behavior unchanged while making new call sites clearer

Validation

• updated existing wait queue test call sites to use the new API
• reviewed compatibility wrappers to ensure old behavior is preserved

Risk

• low
• the old APIs are still present and forward to the new implementation
