CMake: remove BLENDER_SORTED_LIBS

Use CMake's target_link_libraries instead of manually maintaining
library dependencies in a single list.

In practice adding new libraries often ended up being guess-work,
now each library lists the libraries it uses.

This was used for the game player executable so libraries
could optionally link to stubs.

If we need this functionality it can be done using target-properties
as described in T46725.
