Depsgraph: refactor tagging after time changes

This reverts {rB1693a5efe91999b60b3dc0bdff727473b3bd00bb}
and implements an alternative solution.

The old patch had the problem that the depsgraph would always
evaluate at the current frame of the original scene (even when
`DEG_evaluate_on_framechange` was used). Now it is possible
to evaluate the depsgraph at a specific frame without having to
change the original scene.

GPencil: Rename .h to .hh for C++ header files

This follows the new naming rules

GPencil: Avoid double geometry update when trace a stroke

As the sample function is already calling the update function, it's not needed to call again.

Silence `-Wmaybe-uninitialized` warning on GCC/Linux

Add `-Wno-maybe-uninitialized` option to `CMAKE_CXX_FLAGS_RELEASE` and
`CMAKE_CXX_FLAGS_RELWITHDEBINFO` variables on GCC/Linux.

In Release builds GCC's `-Wmaybe-uninitialized` warning is unreliable,
and thus causes noise that can drown out other warnings. These warnings
are now silenced in release mode builds.a

Debug builds seem fine, so flags for debug builds are not touched by
this commit.

No functional changes.

Apologies for the noise. I caught a problem with this that I hadn't before. I will

Cleanup: Outliner: LibOverride tools.

Remove useless extra-processing, comments, etc.

LibOverride: Add 'delete and use linked data' operation.

This will re-link all usages of a library override data-block
(including all of its override dependencies) to its reference linked
IDs, and delete those liboverrides.

As usual, it is available in the ID sub-menu of the outliner context
right-click menu.

Part of T76555.

LineArt: GPencil modifier flag change to mode (wrong use of variable).
