  [CMake] Match the Xcode build's approach to bmalloc/WTF/JSC
https://bugs.webkit.org/show_bug.cgi?id=313477
rdar://175703628

Reviewed by Yusuke Suzuki.

Make WTF a .o target rather than a .dylib. Then JavaScriptCore.dylib exports WTF
symbols to client frameworks.

This enables turning on PAS_BMALLOC_HIDDEN, which saves duplicate compilation
of bmalloc.

Also adopt the WTF prefix header.

Total build speedup is about 2s in clean or touch-one-file build.

* Source/WTF/WTFPrefix.h: Just CMake things.

* Source/WTF/wtf/PlatformMac.cmake:

* Source/WebGPU/WGSL/CMakeLists.txt: Link JavaScriptCore like we do in the
Xcode build.
* Source/WebGPU/WebGPU/CMakeLists.txt: Ditto

* Source/bmalloc/PlatformMac.cmake: Adopt PAS_BMALLOC_HIDDEN.

* Source/cmake/OptionsMac.cmake: WTF can be a .o target now, which is faster.
