Mark Goddard b685ac44e0 Performance: replace unconditional include_tasks with import_tasks
Including tasks has a performance penalty when compared with importing
tasks. If the include has a condition associated with it, then the
overhead of the include may be lower than the overhead of skipping all
imported tasks. For unconditionally included tasks, switching to
import_tasks provides a clear benefit.

Benchmarking of include vs. import is available at [1].

This change switches from include_tasks to import_tasks where there is
no condition applied to the include.
