[ios] Add support for multiple app bundles in the runtime pipeline for a test directory

[kotlarmilos]

Description

The test infrastructure for apple mobile targets doesn't support multiple app bundles in a single test directory. In the case of Mono, a single app bundle is created, and test wrappers are generated to pass the main entry using an environment variable. However, with Native AOT, separate app bundles are required for each test project since the main entry point can't be passed as an environment variable.

Tasks

• Avoid generating test wrappers for iOS tests
• Update the runtime pipeline to discover tests using project files instead of test wrappers

Additionally, the runtime pipeline should be updated to do AOT compilation and app bundling in a single msbuild task in order to inherit project props from the project file.
