IOS TestFlight Non-public API usage error ITMS-90338 for __dyld_find_unwind_sections using NativeAOT

[charlesroddie]

Description

We are testing our app with NativeAOT and attempted to upload a build to TestFlight.

We got an ITMS-90338: Non-public API usage error about __dyld_find_unwind_sections.

There were initially many additional symbols complained about, but these went away when we set invariant globalization.

Reproduction Steps

Upload a NativeAOT-compiled iOS app to TestFlight
To see the smaller error message described here, set globalization to invariant.

Expected behavior

No errors

Actual behavior

ITMS-90338: Non-public API usage - The app references non-public symbols in 50iOS: __dyld_find_unwind_sections
