feat(ios): share DerivedData with Xcode and speed up incremental builds

DerivedData moves into platforms/ios/build through the per-user WorkspaceSettings, so CLI and Xcode builds reuse each other's output. Settings that made the two builds differ come off the xcodebuild command line: -sdk and forced explicit modules are gone, and the deployment target moves into the Podfile post_install.

Simulator builds target the specific destination, debug device builds use a plain build instead of an archive, and the compilation cache lives in platforms/.cache/ios. Device discovery stops waiting as soon as the requested device is found.
