Support custom sfSymbols for iOS

[Xaeryan]

If I add a custom sfSymbol to my asset catalog in the Xcode project, it can be referenced normally in the native project, by name. It also works in libraries such as react-native-sfsymbols. However in the Native Stack "unstable_headerLeftItems", only the built-in sfSymbols work. Can support be added for custom symbols so we aren't restricted to the built-in icons?

unstable_headerLeftItems: () => [ { type: 'button', icon: { type: 'sfSymbol', name: 'custom.drawer', }, onPress: () => navigation.openDrawer(), } ]

Hey @Xaeryan, isn't your request identical to #3395? If so let's keep the discussion there.

Ah yes, I've been searching based on sfSymbols and didn't come across that. I'll add some input there.

Closing as duplicate of #3395
