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

The build system no longer uses `PYTHON_EXECUTABLE` but instead uses
`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.

Nikolaj Bjorner 4a870966ad add code to enable unit propagation of bounds 
set UNIT_PROPAGATE_BOUNDS 1 to use the unit propagation version. It applies unit propagation eagerly (does not depend on checking LIA consistency before final check) and avoid creating new literals in most cases

simplify assumptions and only replay assumptions after constraints are simplified. This allows simplifying assumptions with the current set of constraints independently of whether there is another check-sat.
