fix: do not define _LIBCPP_ABI_NAMESPACE=Cr for all native modules (#34932)

This define is only needed when linking against Chromiums libc++ which we currently
do not ship / expose the symbols of.  We probably should make those symbols visible and
actually ensure that electron-rebuild et. al link against our libc++ instead of the system libc++
but for now this fixes compilation issues on macOS where the default system clang links to the system libc++
which does not (obviously) use the Chromium ABI namespace.

For our nan tests which do link against Chromiums libc++ we define the ABI namespace in the spec runner.

-Subject: build: define _LIBCPP_ABI_NAMESPACE as Cr to align with chromium
-
-Without this define native modules will be built trying to link to _LIBCPP_ABI_NAMESPACE which is the default name, chromium overrides this to Cr for PDB size reasons but they override it on all platforms.  Setting this define allows native modules to actually work. This should not be upstreamed as it is Electron specific.
