Fix #79242: COM error constants don't match com_exception codes
Because a `HRESULT` is a `LONG`[1], no special treatment is required on
x86 platforms to get appropriate values. On x64 platforms we prefer
positive values, what we could accomplish by casting the `HRESULT`
value to `ULONG` and then to `zend_long`, but since the current
behavior is correct and the performance improvement is negligible, we
defer that to master.
