After fixing a bug in the related stuff in coreclr, the regression test has revealed that the NativeAOT version has a similar issue. The exception stemming from the custom query interface are not caught and transformed to HRESULT, so they are reported as unhandled exceptions. This change adds try / catch to catch the exception and translate it to HRESULT.

Pull Request Overview
This PR fixes exception handling in NativeAOT COM custom query interface implementation to match a similar fix applied to CoreCLR. The issue was that exceptions from custom query interface calls were not being caught and converted to HRESULTs, causing them to be reported as unhandled exceptions instead of proper COM error codes.
- Adds try-catch block around custom query interface calls
- Converts caught exceptions to HRESULT return values
- Ensures consistent COM exception handling between CoreCLR and NativeAOT
