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.

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`.
