This typedef doesn't match the signature below, specifically the
signature takes a `lldb:SBDebugger` vs this was defined as
`lldb:SBDebugger&`.
```
lldb/source/API/SBDebugger.cpp:199:13: runtime error: call to function lldb::PluginInitialize(lldb::SBDebugger) through pointer to incorrect function type 'bool (*)(lldb::SBDebugger &)'
.../CustomPlugin.cpp:134: note: lldb::PluginInitialize(lldb::SBDebugger) defined here
```
