Including a public ProvidableCompositionLocal causes linking for iOS targets to fail

[xxfast]

Describe the bug
I have a ProvidableCompositionLocal defined as

val LocalUnit: ProvidableCompositionLocal<Unit> = staticCompositionLocalOf { }

This causes linking to fail

> Task :app:ios-compose:linkPodDebugFrameworkIosSimulatorArm64
Unbound public symbol IrSimpleFunctionPublicSymbolImpl: androidx.compose.runtime/CompositionLocal.current.<get-current>|-5302841245303420610[0]

Current workaround is to mark these either private or internal

private val LocalUnit: ProvidableCompositionLocal<Unit> = staticCompositionLocalOf { }
// or
internal val LocalUnit: ProvidableCompositionLocal<Unit> = staticCompositionLocalOf { }

Affected platforms
Select one of the platforms below:

• iOS

Versions

• Kotlin version*: 1.8.10
• Compose Multiplatform version*: 1.3.1
• OS version(s)*: iOS 16.2
• OS architecture (x86 or arm64): arm64

To Reproduce
Steps and/or the code snippet to reproduce the behavior:

1. Checkout xxfast/NYTimes-KMP@add79ab
2. Open app/ios/ios.xcworkspace from xcode and run

Expected behavior
iOS targets to support ProvidableCompositionLocal similar to android and desktop targets

Another workaround is to add an annotation:

@HiddenFromObjC
val LocalUnit: ProvidableCompositionLocal<Unit> = staticCompositionLocalOf { }

It can be added to properties and functions (you may try it for other issues you reported).

Our goal is to fix it so there won't be a need to use internal or the @HiddenFromObjC annotation.

The fix is available with Compose Multiplatform 1.4.0 when used with kotlin 1.8.20
