feat: replace instruction annotation with work suspendDispatching field

[vie-serendipity]

What type of PR is this?

/kind deprecation
What this PR does / why we need it:
Replace propagation.karmada.io/instruction with suspendDispatching field. Annotation was just a temporary solution. With the native support of the work API, we should deprecate the use of annotations and utilize the work field instead.
Which issue(s) this PR fixes:
Fixes #5386

Special notes for your reviewer:

Does this PR introduce a user-facing change?:

Users who are still using annotations to suspend work should migrate to the `suspendDispatching` field as soon as possible.
