build system: support module local definitions
This introduces a new helper function,
qt_internal_add_repo_local_defines and makes use of it in
qt_internal_add_{module,test,executable,benchmark,plugin}. That function
checks whether QT_EXTRA_INTERNAL_TARGET_DEFINES is set. If it is, the
defines listed in there will be aded to all targets passed to the
functions mentioned above.
The intended usage is that QT_EXTRA_INTERNAL_TARGET_DEFINES gets set
in the repository local .cmake.conf. This allows e.g. opting in to
source incompatible changes in leaf modules (as long as those are
guarded by some define).
Pick-to: 6.2 6.3
Fixes: QTBUG-101640
Change-Id: I06c3693ee69f46e95a48de724621f0c97e7cc3a8
