[DO NOT MERGE] Release/4.18.0

[NachoSoto]

New Features

• Introduced Custom Entitlements Computation mode (Custom Entitlements Computation mode #2439) via Andy Boedo (@aboedo)
• Create separate SPM library to enable custom entitlement computation (Create separate SPM library to enable custom entitlement computation #2440) via NachoSoto (@NachoSoto)

This new library allows apps to use a smaller version of the RevenueCat SDK, intended for apps that will do their own entitlement computation separate from RevenueCat.

Apps using this mode rely on webhooks to signal their backends to refresh entitlements with RevenueCat.

See the demo app for an example and usage instructions.

This includes #2442 cherry-pick, which isn't approved yet. I can update the commit if any changes are required there.

[aboedo]

When we ship, let's manually edit release notes to explicitly mention the new mode and provide a link to the readme in the sample app since it contains usage instructions

[NachoSoto]

Updated release notes here.

[NachoSoto]

Just need to cherry-pick #2452, will do that in a couple of hours.

[aboedo]

@NachoSoto I cherry-picked it to 4.17.11 and rebased 4.18.0 on that one, since it looked like that was the logic applied to the rest of the commits

[NachoSoto]

Yup perfect!

[aboedo]

APITester doesn't work because it's using main, and in main we have a reference to signatureVerificationFailed in API tests (from Trusted Entitlements)

[NachoSoto]

APITester doesn't work because it's using main

It shouldn't be using main, the CircleCI job is supposed to change main to the commit hash it's testing. Investigating.

[NachoSoto]

Oh I see, we needed to modify the cherry-picked commit slightly to accommodate the current API in that branch. Fixing.

[NachoSoto]

Fixed, rebasing.
