Ci cibuildwheel migration

[CavRiley]

Consolidates all wheel building workflows into single workflow file that leverages the pypa/cibuildwheel action. cibuildwheel configuration is located within the pyproject.toml file which allows users to still build wheels locally without copying configuration flags from the workflows into the CLI.

Windows C++ tests (which was handled by ops/build-windows.bat) move to the existing coverage job, since the wheel build no longer compiles them.

Closes #667
