Simplify copts handling and expose them as a build variable

This cl changes copts to be immutable (and changes addCopts methods into
setCopts, so it's simpler to reason about copts) and exposes copts as a build
variable. It also introduces CompileBuildVariablesTest, similar to
LinkBuildVariablesTest, to test that right build variables are exposed for right
actions.

RELNOTES: None.
