Nikolaj Bjorner b52fd8d954 add EUF plugin framework. 
plugin setting allows adding equality saturation within the E-graph propagation without involving externalizing theory solver dispatch. It makes equality saturation independent of SAT integration.
Add a special relation operator to support ad-hoc AC symbols.

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.
The with statement should offer a more concise and safer
alternative to explicit usage of push() and pop() methods.

Fix syntax warning when using Python 3.12. (#7022) 
This happens when generating the Python API and you are using
Python 3.12 in the build environment:

```
.../z3/scripts/update_api.py:1828: SyntaxWarning: invalid escape sequence '\#'
```

This was a `DeprecationWarning` previously, but Python 3.12 changed
it to a `SyntaxWarning` to make it more visible. The release notes
indicate that this will be a syntax error in the future.

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`.

cmake: Require cmake 3.16 or later. (#7015) 
Support for requiring cmake < 3.4 may go away soon (according to
a deprecation notice when building).

Ubuntu 20.04 provides cmake 3.16 and current is 3.27, so that seems
like a reasonable version to require.

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.
