gdb: check for groups with duplicate names in reggroups:add
In the downstream ROCm GDB port, we would create multiple register
groups with duplicate names. While it did not really hurt, it certainly
wasn't the intent. And I don't think it ever makes sense to do so.
To catch these, change the assert in reggroups::add to check for
duplicate names. It's no longer necessary to check for duplicate
reggroup pointers, because adding the same group twice would be caught
by the duplicate name check.
