Resolve some default error warnings (#7191) (#7196)

DxilContainerValidation.cpp has some int / bool comparisons that cause
default error warnings in some of the private builds. This needs to be
addressed. This PR changes the comparisons by converting the numerical
expressions into the appropriate boolean, then comparing the booleans.
