Update platform support and require symengine #10902

Summary

This commit updates our platform support matrix to reflect upcoming changes. The first is that in Rust 1.74 the Rust programming language is raising their minimum support macOS version to 10.12, so Qiskit is raising it's supported version of macOS to match this. The second change is making symengine a hard requirement. We previously had symengine as a requirement only on platforms that had precompiled packages available. But, the percentage of our user base that runs qiskit on those platforms is very small, and maintaining dual support for symengine and sympy adds a lot of complexity around managing the dependencies. This commit promotes symengine to a hard requirement for all users regardless of platform. As a result Linux i686 and 32 bit Windows for Python < 3.10 has been downgraded to tier 3 support as you'll need a C++ to install Qiskit on that platform now (regardless of Python version).

Details and comments

This PR is on hold until after the 0.45.0 release. These platform changes don't apply to the 0.45.0 release, I just wanted to push them up earlier so we can debug any potential issues prior well in advance of making the change.

This should be ready to go now, I fixed the bug with symengine in: 4bdcc20. I'm going to open a standalone PR for that though so we can backport it to 0.45.1 (I'll remove the release note once I do).

mtreinish added a commit to mtreinish/qiskit-core that referenced this pull request Nov 16, 2023
This commit fixes an issue with the use_symengine flag on the qpy.dump()
function. Previously in certain conditions a symengine expression that
was listed in the qpy header as being encoded via symengine was
incorrectly being serialized using sympy. This would cause a failure on
deserialialization as the qpy payload was invalid and symengine could
not parse a symengine representation.

This was originally caught during the development of Qiskit#10902 as that
switches the default of use_symengine to ``True`` as it makes symengine
a hard requirement. This commit splits it out so the isolated fix can be
backported to 0.45.1.

Rust 1.74 released yesterday so the importance on this PR is increased a bit since whenever we tag a release we'll be pulling that in and won't be able to build binaries that are compatible with macOS 10.9. I do think we should wait for #11261 first though and then rebase this on top of that.

Sorry for the chain of inline comments on the reno, I should have probably read it all at once and made a single suggestion. But these are all minor, overall LGTM.

should we keep the comment explaining why we are pinning symengine to <0.10?

Yeah, normally I'd agree and add it back. But, #11262 uncaps the symengine version. So I don't think it matters too much anymore.
