[#24584] Fix TypeObjectRegistry null pass to a callee

[Danipiza]

Description

Issues when building natively on macOS (aarch64-darwin) with clang 21 + libc++ from Nix.

• TypeObjectRegistry.cpp:2620error: null passed to a callee that requires a non-null argument [-Werror,-Wnonnull].
  ...build_annotation_parameter_value(!value.empty() ? value : 0);

I was able to patch this by replacing 0 with empty str literal.

@Mergifyio backport 3.2.x 2.14.x
