Update WW3 to uses CPP instead of switches

[JessicaMeixner-NOAA]

Description

Update WW3 submodule pointer to use CPP flags instead of the current WW3 switch preprocessing.

Solution

Update submodule of WW3 to use CPP flags instead of the current WW3 switches. This does not change answers, and it's important to point that out. However a recent commit of WW3 changed answers so this should go after that PR by @aliabdolali.

Alternatives

None as of now. Early versions of this have been tested on gaea.intel, wcoss-dell, hera.intel and orion.intel. Before this PRs turn in the queue getting help to tests this on other platforms would be good.
