[LOCAL][CI] Require cocoapods to hermes-engine podspec (#45134)

* [LOCAL][CI] Require cocoapods to hermes-engine podspec

* Refactor Hermes workspace (#45071)

Summary:
This change is the first step in refactoring GHA so that they can be reused more easily across jobs.
Its goal is also to be more reliable w.r.t. caches.

That this change do:
* moves `prepare_hermes_workspace` to a composite action
	* saves the `prepare_hermes_workspace` caches only on main
	* uploads the destination folder as an artifact so that we can use it later in the run
* makes the `test-all`, `nightly` and `publish-release` workflow use the new composite action
* updates the `setup-hermes-workspace` to download and use the artifact uploaded by `prepare_hermes_workspace`

[Internal] - Factor out the prepare_hermes_workspace action
