[SDA] Fix naming conflict resolution

Resolving name conflicts by selecting last in flat tree order was
already implemented behind a flag. The same flag was used for making
names global by default. This patch decouples conflict resolution
from global scope. Though resolutions on the same issue (#12581)
handling the full set of resolutions requires updating more tests,
which in turns entails more risk, and potentially slowing the upstream
merge. Remaining resolutions on this issue will be tackled in follow
up CLs.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
