rtems: Add rtems_task_construct()
In contrast to rtems_task_create() this function constructs a task with
a user-provided task storage area. The new directive uses a
configuration structure instead of individual parameters.
Add RTEMS_TASK_STORAGE_SIZE() to calculate the recommended size of a
task storage area based on the task attributes and the size dedicated to
the task stack and thread-local storage. This macro may allow future
extensions without breaking the API.
Add application configuration option
CONFIGURE_MINIMUM_TASKS_WITH_USER_PROVIDED_STORAGE to adjust RTEMS
Workspace size estimate.
Update #3959.
