…ng#8994) (swiftlang#9011) Removes the hardcoding of the contents of the prebuilt libraries. Adds a --version argument to specify which versions of swift-syntax you want to build for. You can have multiple of these. We add a sample build.sh script to the folder to show an example, including finding the most recent prerelease of 602. Also removes the hardcoding of the list of products that go into the library. Instead we ask the package for its list of library products and add them all. Finally, removes the header files since SwiftPM now hooks up the include paths to the CModules from the source in the checkouts. This is needed in 6.2 to support prebuilts generated with that version of the toolchain. I have tested this on all three host platforms including all Linux distros with both architectures and swift-syntax 600, 601, and the latest prerelease of 602
…ng#9112) We are running into cases where, if the Windows prebuilts build runs last, it's the one producing the prebuilts manifest. Since we're using RelativePath to for the library include paths, it's resulting in Windows paths being used and that fails on the other platforms. This change makes sure we always use forward slashes which will work on all platforms. Note to do this we're copying over the manifest types to the BuildPrebuilts script temporarily to so we don't need to make changes in 6.2.0. We'll revisit this for the next release where we probably should use per platform JSON files.

Cherry pick of #8994 and #9127 to 6.2.1
8994 added the ability to build prebuilts and pass in the swift-syntax versions to build for. This was added to 6.2 after the 6.2.1 branch was created. We should make sure 6.2.1 has the same features in case we want to build the prebuilts from that branch. It also avoids a merge conflict with 9127.
9127 Fixes a bug where if Windows prebuilts built last, the include path to the C shims had backslashes in them instead of slashes. This forces them the other way. That unfortunately breaks the signature on the Windows client so this fixes the client to switch them back after signature verification.
