Pull Request Overview

Reverts the temporary trimming analyzer workaround in the netstandard2.0 build targets so that trimming warnings are once again enabled.

• Removed the conditional <PropertyGroup> that disabled the trim analyzer and suppressed related warnings.
• Restored default trimming analyzer behavior for non-AOT, non-full-trim, non-explicit-suppression scenarios.

@rolfbjarne seems still lots of warnings on the sample apps , device tests etc.. is there anything else other than ignore the warnings ?

[rolfbjarne]

@rmarinho do you have a binlog with some of the warnings? no relevant test seems to show up as failing here: https://dev.azure.com/xamarin/public/_build/results?buildId=146082&view=ms.vss-test-web.build-test-results-tab&runId=4521190&resultId=100038&paneView=debug
