dotnet#67024) * Add a --aot-lazy-assembly-load command line option to load assemblies referenced by AOT images lazily. Note that this requires the assemblies used at AOT time to exactly match the assemblies loaded at runtime, otherwise the runtime will abort when it loads the mismatching reference. * Handle the options added by options.h in mono_jit_parse_options ().

Customer Impact
This PR aims to improve startup performance for MAUI apps using profiled AOT on Android and iOS.
It adds a new option to the Mono runtime to load assemblies referenced by AOT image lazily when they are first needed rather than eagerly when the AOT image is first loaded.
Testing
Manual testing
Risk
Low. The new option is not on by default (although the .NET MAUI team may choose to turn it on by default in certain scenarios). With the option off, we use the old AOT loading algorithm that loads all referenced assemblies eagerly.
