Add Solver.solutions(t) 
For parity with
[z3.rs](https://docs.rs/z3/latest/z3/struct.Solver.html#method.solutions)
.

Having a way to find all solutions is frequently requested:
* https://stackoverflow.com/q/63231398/10477326
* https://stackoverflow.com/q/11867611/10477326

In accordance with the Rust, I did not
[guess `t`](https://stackoverflow.com/a/11869410/10477326).

Suggest eval in ModelRef.__getitem__ error 
This improves the previously cryptic error message. I searched multiple
websites before Google AI suggested using model.eval(arr[0]) for getting
solutions out of arrays.

Alias ArithRef.__abs__ to Abs 
This integrates with the `abs(Int('x'))` Python builtin.

a08e8a99f9 Add -headerpad_max_install_names flag for macOS dylib builds 
This fixes the install_name_tool issue on macOS where the tool fails
with "larger updated load commands do not fit". The linker flag
-Wl,-headerpad_max_install_names ensures sufficient header padding
in the Mach-O binary for install_name_tool to modify install names.

Changes made:
- CMake: Added flag to libz3, z3java, z3jl shared libraries on Darwin
- Python build: Changed flag from ML-only to all macOS builds
- OCaml CMake: Added flag to OCaml stublib build on APPLE

Fixes #7623 (regression in 4.15.5)
