Add 'SWIFT_MODULE_ABI_NAME_PREFIX' CMake variable. This can be used from compiler's CMake so its swift-syntax libraries can have unique names. That avoids symbol name conflicts when compiler libraries (e.g. sourcekitdInProc) is used from binaries linking with swift-syntax (e.g. via SwiftPM) swiftlang/swift#68812 rdar://116951101 (cherry picked from commit 093b895) (cherry picked from commit d8c8695)

SWIFT_MODULE_ABI_NAME_PREFIXCMake variable to swift-syntax libraries. Without this,(lib)sourcekitdInProc.{dylib|so|dll}was unusable if the binary links with swift-syntax via SwiftPM dependency, because sourcekitdInProc's swift-syntax symbols conflict with them. By differentiating the ABI name of the compiler's swift-syntax libraries, it can avoids name conflicts.-module-abi-nameis a well-tested reliable option.SwiftLintin Linux, a runtime error is generated when attempting to Lint a file. swift#68812
