Add USE_D8_DESUGAR option in build/core
Add an option to use D8's desugar instead of the standalone version.
USE_D8_DESUGAR=true m would trigger DCHECK in dex2oat unless
https://android-review.googlesource.com/c/platform/art/+/562595 is
patched in as well.
Bug: 69329508
Test: m && USE_D8_DESUGAR=false m
