Bug 1999317 - Create an artifact of Android Chromium symbols. r=mstange
Update the build flags to include symbols during build time and package
the symbols as a separate artifact.
These symbols will allow engineers to properly profile
chromium-as-release (CaR) tests.
Enabling symbols with the build does increase the build time, but
fortunately not by much (just an additional 10-20 minutes)
