Add checks for TriBITS package dependencies depending on package test group

[bartlettroscoe]

Description

Currently, it seems that TriBITS does not check and error out if there are incorrect required package dependencies depending the package test group. For example, an required upstream package can not have a a lower testing group than its downstream packages. For example, an ST package can't have a required dependency on an upstream EX package. Likewise, a PT package can't have a required upstream dependency on an ST or an EX package.

For example, in Trilinos PR #11599, anPT package STKMiddle_mesh declared a required dependency on the EX TPL CDT which resulted in the automatic enable of CDT when the auto-enable of STKMiddle_mesh in PT testing (see trilinos/Trilinos#11599 (comment)). This resulted in a configure error because the location of the EX TPL is not given in those configurations. This illogical dependency should have been detected by TriBITS and errored out.
