Modify {export,install}(PACKAGE_INFO) commands to inherit version
information from the current project in situations where it seems
reasonable to do so. Add an option to explicitly request inheritance
from a specific project.
This leverages the recently added project(COMPAT_VERSION).
Consolidate InstallPackageInfo's bad arguments tests into only two test
cases that each test multiple invocations, rather than having a single
test per invocation. This makes them match the similar ExportPackageInfo
tests which were necessarily consolidated due to those testing many more
variants (due to differences in the respective interfaces). This will
simplify adding additional tests in the future.
Rename the RunCMake/PackageInfo and RunCMake/CpsExportImport tests to
indicate that they cover CPS generated by the install command. This
opens space for similar tests that will cover CPS generation via the
export command.
