Introduce a new module `TestInternalPrivate`.
Kitware's RunCMake allows to create more granular unit tests using
`cmake -P` scripts instead of configuring, generating and building full
projects.
[ChangeLog][Third-Party Code]
Add upstream cmake's RunCMake test infrastructure module to
src/testinternal/3rdparty/cmake to aid in creation of cmake auto-tests.
