[Mono] Add a workaround for android apps, in order to leverage the feature of trimming compiled methods

[fanyang-mono]

Fixes #88538

When enabling IL trim for Android apps, the size of the app got smaller

• The size of dotnet Android template app apk file: 7.7M -> 7.6M (1.3% smaller)
• The size of assemblies/assemblies.blob from maui template app built for android: 254,396 bytes -> 253,952 bytes (1.21% smaller)

Some other assembly might cause the same problem.

This is a temporary workaround to enable the customers to try out this new feature. I've create an issue to track the task of fixing the real problem behind it. (#90403)

I really don't like this. What is the plan for backing this out before RTM?

This is not needed any more. I've found the root cause of this. See comments at #88538 (comment)
