Change create network UAPI to take a user buffer
To not allow the buffer for a network instance to be changed after
creation, the create network UAPI will now take the network model data
as a user buffer. The content of the user buffer is copied into an
internally allocated DMA buffer that cannot be accessed by the user.
This breaks the current API so the Linux kernel NPU driver version and
the driver library version have been given major version bumps. All the
tests, documentation and other applications affected by the changes have
been updated accordingly.
