[SharedCache] Add a named symbol map

Fixes https://github.com/Vector35/binaryninja-api/issues/6561

- Also tightens the SharedCache class to move only, to prevent accidental copies.
- Also removes some extra copies in FFI when should pass by ref
- Also adds `get_symbol_with_name` to python API

The current named symbol map is populated in a worker thread spawned in the view init. This is because populating the map can take about 1 second.
If we are fine with another 1 second added to the view init time then we can add it serially but I don't think this way is _that_ bad, no analysis consults
this, however a user might add a workflow that would be racing this. So we need to add a mutex.
