https://bugs.swift.org/browse/SR-237 calls for `build-script` and `build-script-impl` to be merged. This commit takes another step towards that goal by moving the logic that finds the path to the `clang` and `clang++` executables up into Python-land. Rather than simply moving all of the logic into `utils/build-script`, this commit moves relevant functions into a new Python module, named `swift_build_support`. This has several benefits: - The logic can be tested. Whereas `build-script-impl` needed to be run in order to verify its behavior, the logic extracted out of it into `swift_build_support` can be tested in isolation. - The logic can be split up into several files without polluting the `utils` directory, which now contains many different files that are unrelated to `build-script`.
