Fix NativeAOT ICU build integration for Apple mobile platforms

[ivanpovazan]

Description

Currently System.Globalization.Native is not being built as part of the build process for targeting Apple mobile platforms with NativeAOT. This implies that applications have to use invariant globalization mode.

Proposal

Support building System.Globalization.Native with NativeAOT when targeting mobile platforms and adjust build integration targets according to the fix:

runtime/src/coreclr/nativeaot/BuildIntegration/Microsoft.NETCore.Native.Unix.targets

Line 67 in 06dd126

<NetCoreAppNativeLibrary Include="System.Globalization.Native" Condition="'$(StaticICULinking)' != 'true' and '$(_IsiOSLikePlatform)' != 'true'" />

Until this is fixed, make sure that applications set: InvariantGlobalization=true
