Build release wheels for tier 1 platforms with PGO (#11502)

* Build release wheels for tier 1 platforms with PGO

This commit adds the infrastructure to build the wheels we publish to
PyPI at release time with PGO. Profile guided optimization (PGO) is a
compiler technique that uses collected data about a typical execution
to inform optimizations the compiler can make about building the output
binary. For more details on PGO you can refer to the Rust [1] and Clang
[2] documention on the topic.

To start the only data collected is from running the qiskit
unittests. This should give us some broad coverage as we'll exercise
everything as we do in the unittests. This also means as we grow our
Rust usage in Qiskit we'll continue to cover that code in the unittests
and ensure we have coverage in PGO too. However, longer term we'll
potentially want to look at dedicated PGO scripts that exercise Qiskit
at larger scale than what we can do in the unittests.
