LOG: [llvm-calc-occupancy] Fix build after SGPR queries moved to TargetParser (#213023)

Urgent buildbot fix for #208727.

That PR was developed before #209848, which moved the SGPR count queries
into TargetParser and removed
`AMDGPU::IsaInfo::getAddressableNumSGPRs()`, so
`llvm-calc-occupancy.cpp` fails to compile on current `main`:

```
llvm-calc-occupancy.cpp:229:41: error: no member named 'getAddressableNumSGPRs' in namespace 'llvm::AMDGPU::IsaInfo'
```

This switches to the equivalent
`GCNSubtarget::getAddressableNumSGPRs()`, which forwards to the
TargetParser version. All other `IsaInfo::*` calls in the file were
checked against the new API and are unaffected.

Verified locally: `ninja llvm-calc-occupancy` builds clean,
`llvm/test/tools/llvm-calc-occupancy` passes, and the reported
addressable SGPR count is unchanged (102 on gfx90a).
