Revert "Merge pull request #37114 from apple/revert-36377-NewDriverDefault"

[artemcm]

This reverts commit 937e1a3, reversing
changes made to c2dc8e3.

A change originally merged in #36377 got reverted in: #37114

The reason for this is because SwiftDriver's CMake build behaves differently when using CMake Version <3.17 and some developers who were using an older CMake started hitting errors.

This PR reverts the revert, bringing back the new driver as the default installation.

Before it gets merged one of two things needs to happen:

• Either bump the minimum required CMake version of Swift to 3.17 or 3.18 (Forum thread discussion: https://forums.swift.org/t/bump-cmake-version-to-3-18)
• Introduce manual workarounds for the CMake issue encountered by the driver build when using older CMake. (paths for an executable need to be specified manually)

@shahmishal looks like PR bots on Linux have cmake 3.16, not cmake 3.17.

[gottesmm]

Actually, I am incorrect. That is the cmake that we are building now. I am going to update to a newer cmake using update-checkout.

[gottesmm]

Once #37210 lands, we should be good to merge this. @shahmishal would be good to update the Linux bots as well so we don't build this. But I think for now I want to unblock this.
