ci: Use uv for all pip installs

[matthewfeickert]

• Use 'uv pip' for all calls to 'pip install' and 'pip uninstall' in CI workflows.
  • c.f. https://github.com/astral-sh/uv/
• Fall back to 'python -m pip' for issue with alternative package index.
  • c.f. Installation of torch from pytorch CPU index fails with 'no wheels are available with a matching Python ABI' astral-sh/uv#3437
• Use '--upgrade' as '--upgrade' uses '--resolution highest' by default, which is similar to the 'eager' upgrade strategy in pip.

[matthewfeickert]

@nsmith- @lgray This is ready for review (assuming all the CI passes).

OS	Python	pip	uv pip
Ubuntu	3.12	2m 17 s	50 s
macOS (Apple silicon)	3.12	2m 0 s	53 s
Windows	3.12	4m 21 s	2m 20 s

These would be faster still if not for astral-sh/uv#3437 requiring a switch to python -m pip at one stage.
