feature: support the additional entitlement / capabilities

[madebydavid]

Reviewing what Godot 4.6 now supports and what ShipThis supports:

Export option	Type	Default	What it does	Implemented
entitlements/increased_memory_limit	bool	false	Adds com.apple.developer.kernel.increased-memory-limit	no
entitlements/game_center	bool	false	Adds com.apple.developer.game-center	no
entitlements/push_notifications	string enum	"Disabled"	Adds aps-environment (Production / Development)	yes but needs renaming
entitlements/additional	multiline string	""	Raw entitlement XML appended as-is	no
capabilities/access_wifi	bool	false	Adds wifi to UIRequiredDeviceCapabilities	yes
capabilities/performance_gaming_tier	bool	false	Adds iphone-performance-gaming-tier	no
capabilities/performance_a12	bool	false	Adds iphone-ipad-minimum-performance-a12 (also added when mobile renderer is forward_plus or mobile)	no
capabilities/additional	PackedStringArray	[]	Extra capability strings added to UIRequiredDeviceCapabilities	no

Our handling for these entitlements is out of date see https://github.com/shipth-is/cli/blob/main/src/utils/godot.ts#L28

• We only look for wifi and push
• We were looking for capabilities/push_notifications but this has been renamed in Godot - we should look for both

TODO:

• Handle old and new names for push notifications
• Add missing entitlements & capabilities
• Implement the "additional" feature which allows a custom list
• Test
• Update documentation - https://shipth.is/docs/ios#5-synchronize-permissions

Regarding the "additional" fields which allow us to specify custom things. I think we only need to implement the entitlements/additional one as the capabilities/additional is just used to update UIRequiredDeviceCapabilities

An example of this being used is in https://github.com/migueldeicaza/GodotApplePlugins?tab=readme-ov-file#configure where they say:

For iOS, set at Project -> Export -> iOS -> entitlements/additional:

<key>com.apple.developer.applesignin</key>
<array>
    <string>Default</string>
</array>

So we could try to parse the xml and then add that to the list of things to sync
