Backport fix for Ccache from 0.74 to main (#44089)

Summary:
Pull Request resolved: #44089

While doing the release of 0.74.0-RC.9, we encountered some failures while building because the committed project had some new flags that have been added by cocoapods and that required Ccache.

However, Ccache is not a hard requirement to run React Native and the build started failing on systems that does not have ccache installed.
That happened because we were missing the piece of code that removed Ccache from the project in case the tool is not installed in the system.

We already committed such commit in the stable branch of 0.74, with [this commit](2b18fdf). This change will port the same fix in main.

## Changelog
[iOS][Fixed] - Make sure to remove ccache scripts when ccache is not installed
