[code coverage] Split linux-code-coverage-generation as builder/tester.

Since our primary objective is to reduce the cycle time for repo-wide
code coverage reports, we'd do better to have compilation and test
running on separate builders.

Lowering priority. At the moment, having the compile/test/report on the same bot makes sense, as the first and the last (compile and report) are resource intensive.  Also, the report requires downloading the instrumented binaries, so splitting increases bandwidth consumption.

I don't think we plan to do this anymore.
