SWDEV-204782 - introduce hostcall
Hostcall is a service that allows a kernel to submit requests to the
host using shared buffers, and block until a response is received. This
will eventually replace the shared buffer currently used for printf, and
repurposes the same hidden kernel argument.
When the runtime launches a kernel that requires the hostcall service it
performs the following actions:
- Launch a hostcall listener thread if it is not already running.
- Locate the hostcall buffer for the corresponding hardware queue, or
create a new one.
- Register the new hostcall buffer with the listener thread.
- Set the hostcall buffer pointer as an implicit argument to the kernel.
