Use correct version of jsi.cpp (#53266)

Summary:
When building the xcframeworks on iOS we're including the file `jsi/jsi.cpp` in the Swift Package. This file is also included in Hermes and React Native should use the hermes version of these symbols. This is even described (but overlooked) in the React-jsi podspec file.

This causes the error seen in the bug addressed by this commit.

The fix is to exclude the `jsi/jsi.cpp` file from the jsi target in our swift package.

Fixes https://github.com/facebook/react-native/issues/53257

## Changelog:

[IOS] [FIXED] - Fixed wrong jsi symbols in use when using React.xcframework

Pull Request resolved: https://github.com/facebook/react-native/pull/53266

Test Plan: Tested using a precompiled xcframework in the reproduction repository.
