Use ECMGenerateExportHeader to manage deprecated API better

Summary:
Allows
* projects linking to KConfigCore/Gui to hide deprecated API up to a
  given version or silence deprecation warnings after a given version,
  using
  * -DKCONFIGCORE_DISABLE_DEPRECATED_BEFORE_AND_AT
  * -DKCONFIGCORE_NO_DEPRECATED
  * -DKCONFIGCORE_DEPRECATED_WARNINGS_SINCE
  * -DKCONFIGCORE_NO_DEPRECATED_WARNINGS
  * -DKCONFIGGUI_DISABLE_DEPRECATED_BEFORE_AND_AT
  * -DKCONFIGGUI_NO_DEPRECATED
  * -DKCONFIGGUI_DEPRECATED_WARNINGS_SINCE
  * -DKCONFIGGUI_NO_DEPRECATED_WARNINGS

  or
  * -DKF_DISABLE_DEPRECATED_BEFORE_AND_AT
  * -DKF_NO_DEPRECATED
  * -DKF_DEPRECATED_WARNINGS_SINCE
  * -DKF_NO_DEPRECATED_WARNINGS
* to build KConfigCore/Gui optionally with deprecated API excluded from
  the build, using "EXCLUDE_DEPRECATED_BEFORE_AND_AT" cmake argument.

Test Plan:
Builds with EXCLUDE_DEPRECATED_BEFORE_AND_AT set to 0, 4.0.0, 5.0.0,
5.11.0, 5.24.0, 5.39.0, 5.42.0, CURRENT.
