Add __enter__ and __exit__ methods to Solver class (#7025) 
To enable the usage of the with statement for the Solver class
instances, this commit adds __enter__ and __exit__ methods.

cmake: Use FindPython3. (#7019) 
`FindPythonInterp` has been deprecated for a long time and is more
verbal about that deprecation now.

`Python3_EXECUTABLE`.

Nikolaj Bjorner b9455c3692 #6999 deal with implicit assumptions, more robust pattern matching 
The code is making some assumptions that arrays are 1-dimensional. This is not generally true.
Introducing pattern matching to ensure the assumption is met.
Avoid get_arg(..) especially when there is an approach based on pattern matching recognizers.
