Use X86_64 and C_LOOP OFFLINE_ASM_BACKEND on Windows
https://bugs.webkit.org/show_bug.cgi?id=277631

Reviewed by Yusuke Suzuki.

By using the X86_64 and C_LOOP backends on Windows and getting rid of
X86_64_WIN and C_LOOP_WIN, it helps prevent regressions caused by
forgetting to add "or X86_64_WIN" and "or C_LOOP_WIN" everywhere.
