Reviewed by Yusuke Suzuki.

There was a recent patch titled "Fix the Mac JSCOnly build" (257142 at main), but it's still broken, so let's fix it for real.

* Source/bmalloc/CMakeLists.txt:
* Source/cmake/WebKitCompilerFlags.cmake:
Ensure that compiling "C as C++" uses an appropriate standard.

* Source/bmalloc/libpas/src/libpas/pas_bitfit_page_inlines.h:
Ignore cast-align warnings when this header is included from outside bmalloc.

* Source/bmalloc/libpas/src/libpas/bmalloc_heap_inlines.h:
Remove unused ignore for non-bmalloc targets.

* Source/bmalloc/libpas/src/libpas/pas_utils.h:
Restrict scope of ignore.
