  [Win] clang-cl 19 reports "error: unknown token in expression" for inline asm
https://bugs.webkit.org/show_bug.cgi?id=280029

Reviewed by Don Olmstead.

LLVM clang-cl 19.1.0 couldn't compile module-level inline asm code of
StackPointer.cpp and LowLevelInterpreter.cpp. Added `/clang:-masm=att`
compiler option to use AT&T syntax for inline asm. clang-cl 19
recognaizes `-masm=att` option, but clang-cl 18.
