link/MachO: fix eh_frame handling on macOS

Fixes several issues with eh_frame generation and unwind info on macOS:

* Fix FDE address calculation by including atom_offset
* Store and use pc_range (function size) from FDE for coverage checks
* Avoid creating null unwind records for addresses already covered by
  DWARF FDEs, allowing unwinder to properly fall back to DWARF info
* Remove incorrect addend adjustment in personality pointer calculation

```
