The kernel-doc script identified a few kernel-doc issues in the
scheduler folder, so fix them.

Fix incompatible function pointer assignment.
Define a wrapper around mc timer callbacks to
make them compatible with standard scheduler
message callback function signatures.

The scheduler watchdog timeout is currently fixed at 10secs.
There are few customer use cases, where the CPU is busy for
sometime and the scheduler message processing is taking longer than
the coinfigured watchdog timeout value.
Add a new API to be able to configure this value different than the
default as per the requirement.

This fixes a CFI failure in callback assignment.
Currently, the callbacks in scheduler_msg are void function
pointers. Update them to have a defined type as
scheduler_msg_process_fn_t to catch type mismatch during
compilation.
Other changes to conform to this new type include:
1. Cast callback to qdf_mc_timer_callback_t when
referencing, and back when assigning
2. Cast wlan_serialization_generic_timer_cb to
take fit into scheduler_msg
3. Cast target_if_vdev_mgr_rsp_timer_cb to fit
into scheduler_msg

The scheduler maintains a history of the recent messages
in the scheduler that were queued, started or completed execution.
This information can be reviewed while debugging issues
if the scheduler is taking longer to process any message.
The new API will print the scheduler history on request.

spent in queue, and the depth of the queue at the point of insertion.

Currently the scheduler is unaware of the source module
which posts the message to another layer.

logging, modify current infra, to include the src,
dest in the qip argument of the API

Currently, the scheduler thread keeps a large, pre-allocated array of
messages for use in message posting. The vast majority of the time,
however, the scheduler thread has zero or one messages pending in the
queue. This leads to a huge memory overhead for nominal driver
operation.
Replace the current pre-allocated scheduler message pool with a
hybrid static/dynamic approach.

A commonly used and robust life-cycle pattern consists of the following
4 steps:
1) create (allocate resources)
2) start (mark resources as safe for use)
3) stop (mark resources as unsafe for use)
4) destroy (deallocate resources)
This pattern effectively prevents access to uninitialized and freed
resources. While the dispatcher psoc life-cycle follows this pattern,
the global life-cycle is condensed into steps 1 and 4. Unsurprisingly,
this led to uninitialized and freed resource access problems, especially
in regards to the scheduler thread.
Split the scheduler init and deinit life-cycle functions into init,
enable, disable, and deinit. Create new global enable and disable
dispatcher functions, and call the new scheduler APIs as appropriate.
This brings the global dispatcher life-cycle in line with the existing
psoc life-cycle, and prevents many scheduler related resource access
issues.
