Tests: Port GenerateExportHeader test to RunCMake infrastructure This will allow build failure cases to be added later.

Tests: Add failure test for GenerateExportHeader Modify notation of statements in the GenerateExportHeader test expected to result in link errors. Modify script used to build the test to also generate a suite of modified sources, each having exactly one of the failing lines enabled, and to generate EXCLUDE_FROM_ALL executables for the same. Modify RunCMake script used to drive the test to read the list of such executables and try to build each of them, verifying that they do in fact fail to build. This will verify that the _NO_EXPORT macros are working as expected, and will also catch errors like the one that commit 0cbaaf2d (GenerateExportHeader: Fix add_compiler_export_flags regression, 2016-09-01) fixed. When setting up the failure tests for GenerateExportHeader, check if the compiler actually hides non-exported stuff. If not, the failure tests won't fail, and will cause the overall test to fail. Since this typically is only the case for very old compilers, simply skipping them as opposed to trying to do something more fine grained seems reasonably safe.
