py: Use exceptions instead of returning error codes
...
We have multiple methods which return an error code, mimicking the C++
API. Using exceptions is more natural in the Python API, so change all
those methods to raise an Exception instead.

py: Switch to non-blocking eventfd
...
Blocking wait can be easily implemented on top in Python, so rather than
supporting only blocking reads, or supporting both non-blocking and
blocking reads, let's support only non-blocking reads.

py: examples: Add simple-cam.py
...
Add a Python version of simple-cam from:
https://git.libcamera.org/libcamera/simple-cam.git
Let's keep this in the libcamera repository until the Python API has
stabilized a bit more, and then we could move this to the simple-cam
repo.

py: examples: Add simple-continuous-capture.py
...
Add a slightly more complex, and I think a more realistic, example,
where the script reacts to events and re-queues the buffers.
