CMake: Add a way to use system/bundled 3rdparty libs in bulkHEADdev

[ChangeLog][CMake] Added the configure feature 'force-system-libs'.
Enabling this feature enables every 'system-foolib' feature, and the
system-provided 3rdparty library foo will be used. If the library is not
found, an error is yielded. Also added the analogous
'force-bundled-libs' feature that enforces the usage of bundled 3rdparty
libs.

[ChangeLog][CMake] The configure script gained the options
-force-system-libs and -force-bundled-libs that control the same-named
configure features.

Since we now need a way to mark a feature as "controlling the usage of a
system 3rdparty library", we added the SYSTEM_LIBRARY feature to the
qt_feature command. Patches that add this argument to qt_feature calls
in other repositories follow.

Fixes: QTBUG-96910
