Backport of #96817 to release/9.0-preview1
/cc @carlossanlop @filipnavara
Customer Impact
We noticed when switching from the old to the new ObjWriter that the debug symbols were larger than before.
The important piece of this change is that it groups all the ObjWriter replacement changes into Preview 1, rather than splitting across multiple releases.
Regression
This regression was introduced by the ObjWriter change, which happened a few weeks ago.
Testing
Manual testing
Risk
Medium, because we have very limited unit testing of the symbol quality coming out of Native AOT. This is the primary reason to take this change in Preview 1 -- if we put these changes in ASAP, we can get feedback from users if they broke anything and have plenty of time to change it before 9.0 ships.
