[Build] Pass -target flag to preprocessor invocation in IDL parser
https://bugs.webkit.org/show_bug.cgi?id=306159
rdar://168798872
Reviewed by Ryosuke Niwa.
On Xcode-based builds, it's ambiguous which platform to use when
invoking clang as a preprocessor. All the necessary information is in
the environment, we just need to wire up the -target specifier.
This is important to ensure that <wtf/Platform.h> preprocessor guards
work correctly in IDLs, and to work around some errors seen when testing
the nightly toolchain.
