  -----------
  [OpenMP] Introduce a new worksharing RTL function for distribute

This patch adds a new RTL function for worksharing. Currently we use
`__kmpc_for_static_init` for both the `distribute` and `parallel`
portion of the loop clause. This patch replaces the `distribute` portion
with a new runtime call `__kmpc_distribute_static_init`. Currently this
will be used exactly the same way, but will make it easier in the future
to fine-tune the distribute and parallel portion of the loop.

  -----------
  [OpenMP] Add new worksharing definitions into device RTL

This path defines the newly added `__kmpc_disitrute_static_init`
functions in the device runtime library. These functions are currently
exact copies of the current worksharing method but can be tuned later.
