Drop cxxreact dep from performance/cdpmetrics + timeline Package.swift (#57446)

Summary:
Pull Request resolved: #57446

Catch the Swift Package definitions up to BUCK reality: the BUCK targets for `react/performance/cdpmetrics` and `react/performance/timeline` are already independent of `cxxreact` (`React-cxxreact`/`React-cxxreact` is not in either of their `deps`), but `Package.swift` was still declaring the OSS-side dep. Drop `.reactCxxReact` from both `RNTarget` definitions.

iOS/Swift-Package-only change. No code or BUCK changes.
