Support sync sm3 ce instruction, users can use ce instruction to accelerate sm3 sync task through init2 related functions.

This patch also includes: 1. Add compile parameter and related file to support isa-ce library. 2. Check whether the platform supports the CE instruction in alg driver register process. 3. Make HW driver and INSTR driver of the same alg can be requested at the same time. 4. Support sm3 ce block mode and stream mode for sm3-normal and hmac-sm3.

To prevent users from perceiving the difference in instruction acceleration task, no longer check the specific sched_type, just accept sched_type within the valid range from user, and use default sched_type inside.

As sched_type is checked before init2 calls wd_alg_attrs_init(). Redundancy check is not needed.
