Enable trimming/AOTing in consuming applications #9193
Description
Is your feature request related to a problem? Please describe.
We need to be able to enable consumers of the template engine to use trimmed/AOT modalities, so we need to be trimming compatible.
Describe the solution you'd like.
We need to enable IsTrimCompatible, and then systematically address sources of trim-incompatibility in the codebase. Proof positive would be to have a trimmed or AOT test app that exercises the library in-tree. It's possible that this mode would require a new TFM to the libraries.
There are going to be some very rough areas. Json serialization is easy enough, but the core of the template engine is a reflection-based, delay-loaded, wild-west component system.
