internal/buildcfg: refactor GOEXPERIMENT parsing code somewhat

This CL extracts out a ParseGOEXPERIMENT helper function that parses
GOOS/GOARCH/GOEXPERIMENT values and returns active and baseline
experiment flag sets and an error value, without affecting any global
state. This will be used in the subsequent CL for 'go env' support for
GOEXPERIMENT to validate configuration changes.

The existing package initialization for Experiment and
experimentBaseline and also UpdateExperiments are updated to use it as
well.
