crosperf: introduce cwp_dso and weight for CWP approximation

This patch does initial work to support CWP approximation in crosperf.
It introduceds a global option cwp_dso, which is used to specify the
type of DSO to use for approximation; an option weight in benchmark
setting, which decides the weight of each benchmark in test. This patch
also contains some value checks for these two options.

BUG=chromium:902785
TEST=Passed all unit tests and sample tests locally.
