Do not include -dead_strip when native linking a NativeAOT object file

[ivanpovazan]

This PR disables passing -dead_strip to the native linker in case of NativeAOT runtime to prevent build failures.

Additionally, this change affects the size of the application in the following way - measured with dotnet new maui app version 8.0.0-preview.7.23359.1:

MAUI iOS	-dead_strip	no -dead_strip	diff (b)	diff (Kb)	diff (%)
.ipa (b)	13377583	13435276	57693	57,693	0,43%
Size on disk (b)	41883897	42038873	154976	154,976	0,37%
binary (b)	39614336	39769312	154976	154,976	0,39%

Even though the size of the application regresses, with this change we have a more stable product.

Finally, once this PR gets merged we can open a tracking issue to solve the size regression either by fixing:

• NativeAOT produces static library that makes ld crash dotnet/runtime#88032 or
• by manually removing the dead code as proposed by @filipnavara here: NativeAOT produces static library that makes ld crash dotnet/runtime#88032 (comment)
