Added three cache files: one each for the cross-LLVM and the Swift compiler, the third is a top-level include that pre-defines the lld imported targets `find_package(Clang)` expects. Two existing CMake files gain `SWIFT_HOST_VARIANT_SDK == EMSCRIPTEN` branches for the runtime link and module include paths, which don't affect other hosts. The one non-gated change wraps a `CROSSCOMPILE` swift-stdlib ordering dependency in an existence check. It is a no-op unless that target is absent, which happens only when building against a prebuilt stdlib.
