[iOS][NativeAOT] Adding NativeAOT RunOniOS device test

[ivanpovazan]

Description

This PR adds an integration test for testing NativeAOT running on iOS by extending the existing RunOniOS test method with two new parameters:

• runtimeIdentifier - string denoting the target runtime identifier i.e., on which platform the test will be executed. Since currently CI only runs these tests on simulators (note: referring to iossimulator-x64 in the target path below) https://github.com/dotnet/maui/blob/f9a885219953dd67171b0986f9746795fc5fc207/src/TestUtils/src/Microsoft.Maui.IntegrationTests/AppleTemplateTests.cs#L47 we are passing the same value iossimulator-x64 in all cases for the time being.
• runtimeVariant - new enum type - RuntimeVariant differentiating runtime variants to run the test with (at the moment supported variants are Mono and NativeAOT).

Might need this to also have the AOT: https://github.com/dotnet/maui/blob/5727faa60692a5cc80876fa241cf47634c5f967d/eng/pipelines/common/maui-templates.yml#L43

Thanks. I wasn't aware only RunOniOS is running.

@mattleibow Would it make more sense to add an additional parameter (e.g., bool runWithNativeAOT) on a existing RunOniOS test method instead? The only complication will be the slightly different build properties in case of NativeAOT, but we avoid changing the .yml file.

[jonathanpeppers]

@ivanpovazan I think you could do either one, but maybe merging your test into the existing RunOniOS test is easier?

You could add a bool runWithNativeAOT parameter and set extra MSBuild properties when it's true?

I modified the RunOniOS test and updated the description of the PR according to the changes.

The added test has passed: https://dev.azure.com/xamarin/public/_build/results?buildId=105493&view=logs&j=5577a1a6-5922-5c8f-f8aa-3ff6c6e2bbde&t=01eca571-4306-5a2f-af0e-e1e91b20d32a&l=708

@jonathanpeppers can we merged this, or should we retry to get the CI green?

[jonathanpeppers]

I clicked retry one more time, we might need to /rebase as they fixed some CI things in main recently.

[jonathanpeppers]

/rebase

[ivanpovazan]

@jonathanpeppers I manually rebased and pushed, but I see it can be done with /rebase as well.

~~In any case, it didn't help to get green CI on this PR~~

UPDATE: CI finally passed on another retry ^
