Mac entitlements

I'm writing gdnative haxe (hashlink) bindings and after update to 3.3 encountered problems with registering the library.

There are [calls](https://github.com/HaxeFoundation/hashlink/blob/4c4de37d49cf0ed66b47d20d380fe95bc1bc3ec0/src/module.c#L360) to `dlopen` in hashlink with relative paths and without [`allow-dyld-environment-variables`](https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_cs_allow-dyld-environment-variables) entitlement those won't resolve properly.

Also based on [this line](https://github.com/HaxeFoundation/hashlink/blob/4c4de37d49cf0ed66b47d20d380fe95bc1bc3ec0/src/gc.c#L894) in hashlink source code i assume that [`allow-unsigned-executable-memory`](https://developer.apple.com/documentation/bundleresources/entitlements/com_apple_security_cs_allow-unsigned-executable-memory) is needed too...

The library works fine with official mono build (so this is not about something else).

Is addition of these entitlements too problematic?
