Add OptimizeContext MSBuild target that runs on build

[AndriySvyryd]

Tests tracked by #33136

Even though the compiled model is added to the project, it's not yet discovered, this is tracked by #24893

Fixes #24894

@AndriySvyryd is the idea here to generate the compiled model on every build (during the inner loop), as opposed to on publish? Assuming that we don't have the ability to know when something has changed that requires a model rebuild, is this something we want to do, given that it will make the build much slower?

The idea here is to have a task to generate the compiled model when we decide it should be generated.

We need to measure it first

OK, sure thing.

@JanKrivanek PTAL, thanks.

@cincuranet - no strong concerns from msbuild point of view.
