feat: introduce optional handler strategy

[supervacuus]

This is a very early approach to fix #1026

This is mostly meant for integration in the alpha/beta build sequence of sentry-native, sentry-android, and sentry-dotnet to test against the dotnet-maui on the Android repro project.

No review is required at this stage, just feedback from the downstream test integration.

Great, thanks!

Just to clarify, I intended to provide this branch primarily for downstream testing. I will only merge/release once we know introducing this strategy solves the issue downstream. Also, there is still a TODO item (enable page allocator only when we have a native crash) in the PR that should be done before a merge, not counting any changes required after downstream feedback or adding integration tests that cover the new strategy.

Quick update: We published an alpha release for sentry-java (7.15.0-alpha1) for testing purposes
