Issue #, if available:
By default, git does not pull with recursive submodules pull, resulting in builds with outdated CRT submodule dependency, which in turn results in issues reported such as
#3433
Description of changes:
Add a check validating that the CRT submodule version is one set and validated by the AWS SDK team at the cmake configuration step.
Additionally, add a non-blocking logging error if CRT built-with and runtime-found versions are different.
