-----------
Use NO_UNIQUE_ADDRESS macro instead of [[no_unique_address]] attribute
https://bugs.webkit.org/show_bug.cgi?id=304415
rdar://problem/166795977
Reviewed by Ross Kirsling and Darin Adler.
Windows builds with clang-cl fail to recognize [[no_unique_address]]
even when compiling with C++23. WebKit already has a NO_UNIQUE_ADDRESS
macro in Compiler.h that properly detects compiler support for this
attribute and falls back to empty definition when unavailable.
Replace direct use of [[no_unique_address]] with the NO_UNIQUE_ADDRESS
macro in RefCounted base classes to fix Windows builds while maintaining
the attribute on platforms that support it.
