  Fix 22942 - Check for S_TRHEAD_LOCAL_ZEROFILL alongside S_ZEROFILL

  The code generated an unexpected / invalid header for the `thread_bss`
  section marked as `S_TRHEAD_LOCAL_ZEROFILL`. The generated object file
  is rejected by ld included in newer XCode versions (>= 13.3).

  E.g.
  ```
  ld: section __DATA/__thread_bss has type zero-fill but non-zero file
      offset file '../generated/build.o' for architecture x86_64
  ```

  This patch changes the existing code to treat `S_TRHEAD_LOCAL_ZEROFILL`
  like `S_ZEROFILL` w.r.t. the section size.
