Increases default size of stack used by work queue RX thread from 1024 to 1280 to avoid memory issues. After adding the buffer with the default size of 128 that is allocated on the thread's stack (see #77552), there is too little stack left during heavy stress.

Enable dedicated workqueue thread for the ICMsg backend.
|
|
Disabling this configuration will cause the ICMsg backend to
|
|
process incoming data through the system workqueue context, and
|
|
therefore reduces the RAM footprint of the backend.
|
|
Disabling this config may result in deadlocks in certain usage
|
|
scenarios, such as when synchronous IPC is executed from the system
|
|
workqueue context.
|
|
The callbacks coming from the backend are executed from the workqueue
|
|
context.
|
|
When the option is disabled, the user must obey the restrictions
|
|
imposed by the system workqueue, such as never performing blocking
|
|
operations from within the callback.
