Adding a stage-2 preset. This preset adds SwiftPM and XCTest to the built products. The stage-1 preset could likely build all of the product, but because the stage-1 compiler was built without several optimizations available in the stage-0 compiler, this compiler will not be as performant as a separate stage-2 compiler. (cherry picked from commit 4130bca)

Cherry-pick of: #80921
Adding additional presets for the stage-1 and stage-2 bootstrap toolchains.
These are both intermediate toolchains that are working up to a toolchain capable of building the entire toolchain.
The stage-1 toolchain is built from the stage-0 toolchain, which is missing various optimizations due to the lack of Swift code.
