devlink: Move graceful period parameter to reporter ops

Move the default graceful period from a parameter to
devlink_health_reporter_create() to a field in the
devlink_health_reporter_ops structure.

This change improves consistency, as the graceful period is inherently
tied to the reporter's behavior and recovery policy. It simplifies the
signature of devlink_health_reporter_create() and its internal helper
functions. It also centralizes the reporter configuration at the ops
structure, preparing the groundwork for a downstream patch that will
introduce a devlink health reporter burst period attribute whose
default value will similarly be provided by the driver via the ops
structure.
