Don't force compiler colors by default, add an option for that

[Feature]       Make it possible to compile without colors.
[Cause]         Compilation can be on a terminal (or non-terminal) that
                does not understand them.
[Solution]      Add a cmake option to force compiler colors, by default
                they are "auto"
[Verification]  cmake -DVASUM_BUILD_FORCE_COMPILER_COLORS=true/false
