gh-81057: Vendor a Subset of distutils for the c-analyzer Tool (gh-102505)
distutils was removed in November. However, the c-analyzer relies on it. To solve that here, we vendor the parts the tool needs so it can be run against 3.12+. (Also see gh-92584.)

Note that we may end up removing this code later in favor of a solution in common with the peg_generator tool (which also relies on distutils).  At the least, the copy here makes sure the c-analyzer tool works on 3.12+ in the meantime.
