GH-41480: [Python] Building PyArrow: enable/disable python components by default based on availability in Arrow C++ (#41494) ### Rationale for this change Currently, when building pyarrow from source, one needs to manually enable the optional components through setting `PYARROW_WITH_...` environment variables. However, we could also make a default choice of components based on which ones where enabled in the Arrow C++ build. ### What changes are included in this PR? Set defaults for the various `PYARROW_BUILD_<component>` based on the `ARROW_<component>` setting. Keep the current `PYARROW_WITH_<component>` environment variables working to allow to override this default. ### Are there any user-facing changes?
