Algorithms don't have to be split to prepare/process/postProcess
...
Since it's safe to evaluate parameters in background threads
now, it's usually going to be ok to evaluate everything in
the processAlgorithm step.
This keeps the algorithm code as simple as possible, and will
make porting faster.
Note that the prepare/postProcess virtual methods still exist
and can be used when an algorithm MUST do setup/cleanup work
in the main thread.

Rename QgsProcessingAlgorithm::clone to ::create
...
Since it better describes what the function does. It returns a new
pristine copy of the algorithm, not a clone of its current state

Split algorithm execution into separate prepare/process/postProcess steps
...
The prepare and postProcess steps are designed to be run in main
thread only, while the process step can safely be run in a background
thread.

Improvements to QgsProcessingAlgRunnerTask
...
- take a clone of algs before running them. This avoids issues
if the algorithm is removed or edited while a background task
is running
- accept an optional existing feedback object
