In commit 55e4753bbb (Refactor cmTargetExport removing
InterfaceIncludeDirecories, 2021-07-20, v3.22.0-rc1~337^2~1) the storage
of `INCLUDES DESTINATION` was moved into each target. However, a target
may be installed in multiple exports, and their `INCLUDES DESTINATION`
should not be mixed.
Convert the IncludeDirectoriesEntries vector to a map and modify access
function to store the directories lists with respect to cmExportTarget
object. This fixes error when the same target is exported more than once
via different exports and each for consequent export its include
directories list grows. Add a test for this case.
Fixes: #23183
