Add Cargo Arguments and Cross-Architecture Support (#1777)

* Add passthrough to cargo build

* Add platform_triple flag

* Add handling to bundle and serve commands

* Show full stacked error from Tauri in bundling

Previously only the top-level error was shown, giving only vague data
for debugging the build process

* Adjust bundle platform triple when cross compiling

* Rename --platform-triple to --target

* restore some deleted docs on CLI commands
