feat: add Log directory

[JonasKruckenberg]

Adds api functions that provide access to the suggested log directory. Resolves to BaseDirectory::Home/Library/Logs/{bundle_identifier} on macOS and BaseDirectory::Config/{bundle_identifier}/logs on windows and linux.
It exposes this through tauri::api::path::BaseDirectory::Log and tauri::api::path::log_dir for rust and path.logDir for javascript.
Inspired by electrons setAppLogsPath method and the electron-log package.
