Part of SERVER-80628

We have a large number of platforms, each has its own mongo/config.h definition. To avoid having to manually validate parity between the new Bazel mongo/config.h generator and the old SCons one, automate a check to increase confidence in correctness. A bug in this implementation could impact performance and correctness in subtle ways on any of our supported platforms.

Add a quick validation check on all compile_dist_test executions to validate that the SCons generated mongo/config.h file is the exact same as the new Bazel generated mongo/config.h
