Marc Chevrier 2c71d051fa Makefiles Generators: use compiler for dependencies generation
Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.

The consolidation uses the same approach as `CMake` dependencies management.

Fixes: #21321
